In reply to planetmarshall:
> You can also build strength via hypertrophy, ie growing more muscle fibre, with high volume. However I'm not sure that's really applicable to finger strength, though it might be for forearm strength.
Actually totally correct, it's just that at least IMO the hypertrophy in question is best done on a steep board or bouldering wall whilst also building other aspects of strength and movement precision etc.
I think a fingerboard is the most useful place to really max out the loading efforts on fingers as it's totally static and controlled and very easy to make progressively harder - unlike board training which is far more analogue.
It also means the grip type will be far more varied hence reduced injury and building of finger pulp etc...
All things I'm sure you're already aware of - good for the OP to know though
