To set the record straight:

Here is what he actually said:
pyad wrote:utilising equal sectors was all done by me very long ago, about ten years but on my own site, so I was a little surprised by the reaction here which regarded this as new. I'd overlooked the fact that I hadn't written about it here before so for TMF/TLF readers who were unaware of how I constructed HYPs on my site it was indeed new. But it's only a minor shift and a logical one where HYPers hold sectors containing more than one share.
As a matter of fact, the quotes I actually had in mind when I wrote that were both on the first page of this thread:
pyad wrote:For a long time now Ian I have been defining diversification in an HYP by the number of sectors rather than by the number of individual shares in order to avoid the confusion sometimes created when people refer to the number of shares without explaining whether or not they are all in different industries.
pyad wrote:That, I think, makes it much clearer so I'd refer now to a minimum of 15 sectors rather than 15 shares, in order to cover multi-holding sectors. All the HYPs I've constructed for some years now have had more shares than sectors due to some of the latter having more than one holding.
I'm not suggesting that you or anyone else should have been mindreaders - the pyad quote you give pre-dates my comment, so it was certainly earlier in the thread and I certainly
could have seen it before making my comment. But actually, I hadn't, due (I think) to a combination of starting from a copy of the thread that had been loaded quite a long time earlier and the fact that while the phpBB discussion board software tries to warn one about new replies possibly making one reconsider a proposed reply, that warning happens on the first preview or submission one makes after the new replies, and can be
very easily overlooked when it happens on a preview (the only visual hint on my system that it's happened is that the vertical scroll bar shows that I'm further down the page than I would normally be). The main point of that is just to say that had I been aware at the time that pyad had said that what he'd written before was on his own site, I would probably have worded my comment somewhat differently, or even not made it at all - I'm doubtful now that it really added anything to the discussion!
Also, from a later post:

Invest equal amounts in each share.
That does not say what Gengulphus was asking about i.e. that sectors have to be equal weight, not shares.
That isn't quite what I asked about - my questions (on page 2 of this thread) were to clarify what pyad's advice was on that issue, and it was answered authoritatively by the only person able to do so in the very next post. It wasn't about that issue itself - I don't have any questions about that, and have been quite clear in many other threads about my stance on the issue itself for a long time now. It's that what matters for diversification is excessively
big shareholdings and sector holdings (*) and they're probably best addressed by some sort of limits on the size on a shareholding and the size of a sector holding. There are quite a lot of options within that general approach - whether one measures holding size by capital value or income, how far one places the limits above the average (or median - it seldom makes much difference once one's HYP contains a good number of holdings), whether one makes the limits 'soft' ones that merely prevent topping-up if exceeded or 'hard' ones that force sales if exceeded (or indeed has both, with the 'hard' limit somewhat above the 'soft' limit), etc. Which to choose is a good question, but I don't have any strong opinions on that beyond that the best choice almost certainly depends on the HYPer's objectives, circumstances and preferences (certainly the ones I've chosen for my main HYP and GDHYP differ in a number of respects, due to my objectives and assumed circumstances for GDHYP differing from my objectives and actual circumstances for my main HYP).
Anyway, the point of my question was to establish exactly what pyad's position was on the issue. Having done that and established that it's equally-weighted sectors plus (where relevant) equal weighting of each shareholding within its sector, at least initially for lump-sum-all-at-once HYP construction, I didn't (and still don't) wish to argue with it. That doesn't mean I agree with it - just that IMHO,
any sensible set of rules one sets oneself for a HYP will allow a considerable amount of 'slack' around the weightings it regards as ideal and only take corrective action if the portfolio deviates from it or as a side-effect of actions performed mainly for other reasons - for example, TJH's top-up ranking system, which I'm fairly certain is also HYPTUSS's, is mainly there to help one decide what share to top-up, but because low capital value pushes a share towards the more favoured end of the rankings, it has a tendency to equalise capital weightings (only a tendency, i.e. not saying it does so every time!). I'm pretty certain that pyad's position on the issue would not match my ideal weightings for lump-sum-all-at-once HYP construction, but that it would lie within their 'slack' - so I wouldn't feel any need to take corrective action about diversification if pyad were to hand over a just-constructed HYP bought using his position to me. It seems a bit silly to argue against portfolio weightings I myself would tolerate, and so I have no wish to do so!
I do agree that IanTHughes seems to have somehow overlooked the directly-relevant "Invest equal amounts in each share" part of his quote from something pyad wrote while seeing the might-have-been-relevant-by-implication "Ensure their sectors are diversified." part, and given its date in 2013, it indicates that pyad hasn't been giving consistent advice about that point for as long as he seems to think he has (though having said that, the inconsistent advice could just be the inadvertent result of somewhat careless cut-and-pasting from something he'd written much earlier). But that post of IanTHughes's quoting pyad doesn't quote anyone else, so while it
might have been intended as an answer to my questions, if so it was so off-target I didn't recognise it as such! And I suspect it is far more likely to have been intended as a response to pyad, or to you, or just an extra data point relevant to points expressed on the thread - which it is, though not in the way he appears to have thought it was!
(*) Excessively
small holdings can be a problem, but it's a potential admin problem rather than a diversification problem. I.e. it's to do with the fact that e.g. a holding that is only providing 0.1% of the HYP's total income produces on average just as much admin work as one which is producing 5% of that income, so time spent on admin is on average 50 times less cost-effectively spent for the former than the latter. It doesn't present a high risk to the portfolio's total income - quite the contrary! And if one does find an excessively small holding to be an admin problem, the solution IMHO is either to top it up reasonably soon (to make it only a short-duration problem) or to tinker it away, which depending on its HYP credentials. (If one uses it, TJH's top-up ranking scheme, which AFAIAA is also HYPTUSS's or very close to it, should place it pretty high in the queue for topping up if its HYP credentials are good.)
