If you are serious about the meet, this should take precedence in your training. ask yourself, will this help my bench? with that said, i recommend benching twice a week until one week before the meet. of your 2 day bench split, day one work up to a heavy triple on your competition bench. pay strict attention to form as you only have 4 weeks of actual training to get there and you aware your setup needs lots of help. once you find your max triple try and get a couple extra sets in with the same weight. this day you can also do some tricep work of your choice
on your second bench day work up to a heavy triple on close bench. next do your rack lockouts and do at least a few sets of heavy triples.
i say drop the speed bench, i really believe your form, meaning you revex, will suffer by doing it. next you need to do a day of shoulders, and another for rows, shrugs, pullups, etc. after that you can do whatever you want. i would recommend taking a day off before your bench days to get the full benefit of a days rest before going all out. i know you do events on sunday so i would recommend doing your first bench day on tuesday and your second on saturday.
the week before the meet you should just rest so you really only maybe 8 times to bench before the meet. make the most of them
