Below is part of an email I received from a STM user looking for help on a blinds structure. I'll post my reply below...
I am running a 30 man league for the WSOP, with 10,000T in chips, and 30 minute Blind Levels. I was wondering if you could look at the attached(below) schedules. Since you don't know me, I didn't want to send an excel spreadsheet, although I certainly can if you prefer. There are a few things affecting my decision on the blind schedule:
1. We have increased from 20-30 people
2. I have never used Antes before
3. I would like tournament to finish between 7 & 8 hours. We start at 7pm, and would like to wrap up no later than 3am.
4. I don't want the tourney's to go too long or too short.
All of that being said, here are the schedules:
Original Schedule I proposed to league, but I think it may last too long:
Round Total Time Time SB BB Ante
1 0-30 7:00pm 25 50 0
2 31-60 7:30pm 50 100 0
3 61-90 8:00pm 100 200 0
4 91-120 8:30pm 100 200 25
121-125 9:00pm 5-Minute Break
5 126-155 9:05pm 150 300 50
6 156-185 9:35pm 200 400 50
7 186-215 10:05pm 250 500 50
8 216-245 10:35pm 300 600 75
246-250 11:05pm 5-Minute Break
9 251-280 11:10pm 400 800 100
10 281-310 11:40pm 500 1000 100
11 311-340 12:10am 600 1200 200
12 341-370 12:40am 800 1600 200
371-375 1:10am 5-Minute Break

19 556-585 4:20am 5000 10000 2000
Revised Schedule I came up with that I think will get me closer to my end time goal:

8 216-245 10:35pm 500 1000 100
246-250 11:05pm 5-Minute Break
9 251-280 11:10pm 600 1200 100
10 281-310 11:40pm 800 1600 200
11 311-340 12:10am 1000 2000 300
12 341-370 12:40am 1500 3000 500
371-375 1:10am 5-Minute Break
13 376-405 1:15am 2000 4000 500
14 406-435 1:45am 3000 6000 1000
15 436-465 2:15am 5000 10000 1000
Thanks in advance for any advice you can give me.
