My inspections, all the year round, tend to be as low impact as possible and I agree that you should know your bees sufficiently to be able to know when you need to look a bit further into the box - and I don't think it, necessarily, will take 1000's of inspections to reach that level of competence. But ... and it's a BIG but... there are a lot of beekeepers who still believe that an inspection needs to hunt down the queen, inspect every frame in minute detail, at every inspection... and it is the influence on those people that drives my concerns that we should not be encouraging early inspections and certainly NOT in depth inspections or fiddling out of curiosity.
You, clearly, have the resources where you can, in some cases, resolve some issues that you may identify at an early time of the year, but the average beekeeper does not. If you know you cannot resolve an issue, then it is just fiddling for the sake of fiddling.
The biggest killers of colonies over winter are ineffective control of varroa late in the season and before the winter bees are laid up and a lack of sufficient stores in the hive to see the colony through. The former is not going to be easy to resolve in February - even if you know about it - the latter is easy - if there is any doubt about the level of stores and you lack the experience to determine if the stores in the hive are sufficient, then a slab of fondant, without an invasive inspection, is an easy fix.
As for advice from the NBU .. whilst I am reluctant (not being a proper beekeeper) to suggest that such an august body would offer lousy advice - when you read further into their recommendations you come across this particular advice in regard to their suggested inspections in February or March:

When you are doing spring checks it is a good time to do some spring cleaning such
as scraping the top bars and crown board free of brace comb and other detritus.
Better still clean the top bars and put the frames and bees into a clean hive on a
clean floor board. If you do not have much spare equipment you can scrape out and
lightly scorch the old hive and then use it for the next colony change. You may need
to scrape the floors and collect the debris into bags for Tropilaelaps or cSHB cheks
by the NBU. At the time of writing these will only be for sentinel apiaries agreed by
the NBU"
There are other suggestions in their pamphlet that I would take issue with as well ...I'm not a fan of shook swarms and as far as I know the Small Hive Beetle has not yet got as far as the UK (and the pamphlet stems from 2018 so it's not appeared in the last 6 years either !).
In the light of this advice I'm not sure they are the best source of good information ...
