Morning peeps

What do you guys do in the way of training/practice when shooting 10m ap?

I feel the need to formalise my practice so the resulting cards are easy to score and are of a similar number each sesdion.

Do the NSRA shoot 4 shots per card and ISSF 5? I'm thinking of taking part in NSRA postal comps next year so I guess it makes sense to shoot 4 per target and get used to that course of fire/scoring. Ive also started to use a ISSF scoring app which is really interesting.

I think what I'm trying to get at is what do you think is the right amount of practice cards to shoot during a session so i can access how im scoring?

Thoughts on any of the above much appreciated.
