Good points. So this is my philosophy - you want to get sufficient practice and you want it to be close to competition form. But, putting on tightest suit and wraps and hitting high RPE sets is very fatiguing. So, we need a balance. This is where I have had a lot of success with belt/wrap squatting and looser suit bottoms. I think that the strength curves and technique of this amount of gear is similar enough to a competition lift. So, in keeping with the general principle of high frequency practice, I think that barring some major reasons, gear should be worn every week at times when a meet is within 4 months. If there is a long break between meets, getting in some raw training blocks can be utilized.
To clarify, in the more distant competition period (>8 weeks out), I would do 3 squat sessions per week - 1 suited, 1 belt/wrap, and the third session beltless (not a total rule, but a common pattern). These sessions would all be in the range of prelipins tables, focusing in on 70-85% 4-7x2-5. These are calculated based on the respective maxes for that lift (i.e. calculate the % for belt/wrap based on your best belt/wrap squat, or best estimate based on training).
Deadlift, suit only put on twice before the meet - maybe 7 and 4 weeks out. Otherwise, training comes from same intensity range at frequency of 2-4x per week.
Bench press is mostly done raw, shirt is put on varying number of times before the meet. Maybe 8, 6, 4, 3, and 2 weeks out. Competition shirt might be worn only twice if the lifter is confident in his form. Again, bench is done at high frequency of 3-6x per week and focuses on the same intensities.
