Not that I have a dog in this fight - got an EASA PPL(A)
But I created a basic spreadsheet that calculates this 'within 24 months' status. Others have done the same.
It isn't difficult to keep track of this and the rule is quite straightforward
However I do feel that the LAPL should have a ratings arrangement like the PPL(A) so everyone has a date they can work to. It is obvious that a fair number of pilots are still trying to work to PPL rating rules and failing to recognise it is different.
At our airfield I've seen pilots almost in tears when they realise they've not understood the rules and need to fly as a student for a period
