I think you could just store the signatures centrally for validity, no need to store the whole models.

If a task/chore can be done in 2 minutes or less, do it now.

Not sure if it is the best, but it is a simple piece of advice I follow religiously. I think the reason this makes sense is that the cognitive load of trying to remember to do it is higher than just doing it straight away.

Thanks for the info. Signed.
