10000 in 1000's
Total of 17,000 starting chips
Then instead of
100-100 we do 25-50
then we do 50-100
then 150-300 instead of 100-300
What do you think of that? That would put more chips in play and smaller jumps in the earlier rounds.
If you can introduce T25 chips (and bump starting stacks to 17K), I much prefer using the blind structure below. I have used this structure extensively for 2-table re-buy tournaments (once a month since 2005), and it works really well. Blinds start at 50/100, blind increases average 40%, and all
blind increases are between 33%-50% -- it is a very consistent structure from round to round:
R1 - 50/100, 25 minutes
R2 - 75/150, 25 minutes
R3 - 100/200, 25 minutes
R4 - 150/300, 25 minutes
20-minute break (re-buy ends, color-up T25 chips), TT = 1:40
R5 - 200/400, 20 minutes
R6 - 300/600, 20 minutes
R7 - 400/800, 20 minutes
R8 - 600/1200, 20 minutes
R9 - 800/1600, 20 minutes
R10 - 1100/2200, 20 minutes
R11 - 1500/3000, 20 minutes
20-minute break (color-up T100 and T500 chips), TT = 4:00
R12 - 2000/4000, 20 minutes
R13 - 3000/6000, 20 minutes
R14 - 4000/8000, 20 minutes
R15 - 6000/12000, 20 minutes
R16 - 8000/16000, 20 minutes
R17 - 11000/22000, 20 minutes
20-minute break (color-up T1000 chips if desired), TT = 6:00
R18 - 15000/30000, 15 minutes
R19 - 20000/40000, 15 minutes
R20 - 30000/60000, 15 minutes
R21 - 40000/80000, 15 minutes
With 17K starting stacks and 20 players plus re-buys, the event should end somewhere between R16 and R17, or just under 6 hours (plus breaks).
I would not include a 25/50 round, just to avoid the 100% jump from 25/50 to 50/100. Having 170 big blinds to start with this structure should be plenty.
One of the nice things about this balanced and predictable structure is that you can tailor an event to last however long you want, by altering the starting stack size and/or the blind round lengths.
For example, a two-table event with 10K starting stacks (no re-buys) and:
15-minute rounds will last about 3.5 hours,
20-minute rounds will last about 5.0 hours,
25-minute rounds will last about 6.0 hours,
30-minute rounds will last about 7.5 hours.
For a two-table event with 20K starting stacks (no re-buys) and:
15-minute rounds will last about 4.0 hours,
20-minute rounds will last about 5.5 hours,
25-minute rounds will last about 7.0 hours,
30-minute rounds will last about 8.0 hours.
Best of luck, whatever changes you decide to make (if any!). Hope to see a report back if you do.
