Good Blind Structure For a 15-32 Person MTT SNG?

[4 High]

They use something like...

Start with 2500

5-10
10-25
25-50
50-100
75-150
100-200
200-400
300-600
400-800
500-1000
1000-2000

20 Mins each. I was thinking something like this instead

25-25
25-50
50-100
75-150
100-200 25
150-300 25
200-400 50
300-600 50
400-800 100
500-1000 100

With 30 or 40 Min Intervals and still starting with 2500. Thoughts?
