Tempest in a teapot - IFR 'training' in-between lessons

Just a question for y'all out there.

In-between lessons I've been practicing approaches using my OnTop IFR
program. It seems to work, very well, in terms of getting me to recall the
procedures and frequencies by sheer repetition when it comes to my actual
lesson day.

My question though: Is such an approach (pardon the unintentional pun)
wise/useful? Would it be better for me to go into my actual instrument
lessons totally fresh (of course, with a look-see at the approach charts
before leaving for my lesson) without any rehearsal / practice? I should
say that I do notice a big difference (and satisfaction with) in my
performance on the lesson days where I have practiced/rehearsed the
approaches on my simple Sim on the days before my lesson.

Would be interested in hearing your input!
