I only mention this because I think the travelling was a contributing factor to my cock-up. Anyway, back in February I topped up Hammerson and United Utilities but I discovered this week that I never updated my spreadsheet with these purchases. This lead to both shares still being ranked as optimum top-up candidates. As a result, when I used my accumulated cash later in February I topped up United Utilities again and in my regular monthly top up at the start of March I again topped up Hammerson. This means I've doubled up my top-ups for both United Utilities and Hammerson. Ah well, c'est la vie. However, by a lucky twist of fate, HMSO jumped almost 25 % this week so my portfolio benefitted from my having a bigger holding than planned. Both shares are now overweight being the largest two holdings in the portfolio. They won't need topping up for a while.
I forgot to cancel a cheap-day order a few years ago which resulted in an additional and unintended top up of Vodafone the following month.
It's a molehill, which very likely you won't remember or notice in a few years time.
IMO there's no need to get overly obsessed by weightings/medians etc. or trying to correct these mistakes while one is in "building" phase. I set myself quite a high bar (10% capital or forecast income per sector, 20% capital or forecast income per industry) that I check I stay under with each top up, and am quite comfortable progressing in lumpy steps.
