It seems like that would take a lot longer. IMHO with only 10 days, the best way to up the reps with 225/235 would be to spend some time with the bar every day. Jim Wendler's last article, "How to Bench Like a Stripper" talked about how at least 50 reps every day with an empty bar, focusing on technique, would be very beneficial. Also, some GTG a la Pavel could work too. Lots of doubles or triples with 225, and singles or doubles with 235, and take it real easy a few days before the 21st. Something to think about at least, maybe the guys smarter than me can chime in.
