Meet prep, or as my wife calls foreplay, Meat Prep, is overrated for most people. 99% of the time, they fuck it up because they do something totally stupid like "heavy walkouts" or do 2-3 meets before the meet. Just to make sure they totally fuck up the real meet. it's a good plan.
We switch between 3-6 weeks of FSL/5's Pro work with 3-6 weeks of something harder (BBB, BBS, SSL, conditioning work, etc.) - if you have a meet coming up, just make sure you do 3-6 weeks of harder stuff with 1 week of "easy" at the end.
Just don't try to make up 12 weeks of not training hard by forcing more volume AND intensity into final 3 weeks. Mental midgets drive me nuts.
