8/8/4/7 = 270 base chips for 10 people, 15 rebuys possible with 30x T5000, bringing to 300 chips
8/8/8/5 = 290 base chips for 10 people, only 5 rebuys possible with 10x T500, bringing to 300 chips, not practical
12/12/5/6 = 350 base chips for 10 people, 25 rebuys possible with 50 x T5000 bringing to 400 chips
I don't necessarily see a case for 500 chips for a single table of 10.
