Ok I'm helping some on a local fund raiser for a local community center NLH tournament. They want to do the buy in for $100 = 2000 in chips $50 add on = 2000 in chips what would be a good breakdown starting with $5 and $10 blinds? 20 minute blinds. Should have 50-75 players.

Duration will be Up to 5 hours I think that is a regulation of the state gaming commission.

No 500s?

A "standard" breakdown for a T5 base tourney with T2000 starting stacks is
10 × T5
10 × T25
7 × T100
2 × T500

Addons and rebuys could be handled with T500 and/or T1000 chips. The real challenge is estimating a rebuy rate (the amount of rebuys and addons) and cutting of the rebuys at a certain level to achieve this rate, then based on the total nr of estimated chips in play (which depends on the rebuy rate) construct a blinds structure to meet the 5h deadline.

I usually try to contribute to structure threads, but charity events are a bit different and I have no experience of them, so I will quietly bow out of this one.

Building a starting stack breakdown and blind structure requires:
  • Length of time (5 hours)
  • Number of players (somewhat vague at 50-75)
  • Rebuys (yes)
  • Chips - the amount of each denom (?)
With any one component missing, I can't make or recommend any breakdown.

Also lost with the 50s but no 500s.

But I will say this: If 75 players attend, everyone adds on and the rebuyrate is ~50% (lets round to 40 players) then there will be 2000×(75+75+40)=380000 chips in play, and the "20 big blind rule" suggests the tourney should end no later than at the 10000/20000 level. If the deadline is hard, I would set this a level early.
With 4 color-up breaks of 10 minutes, that's 240 minutes of poker. 20 minute levels means 12 levels. You have to get from 5/10 to 10k/20k in 12 levels. It's gonna be a turbo. I think you need to shorten the levels.

This might work:

One rebuy or addon per person, no more. Stacks are 1000.
Worst case there's 150000 at play, putting the last level somewhere around 4000/8000.
15 minute levels.

300 minutes in total, minus a level to not break the deadline, minus just 2 breaks of 15 minutes, should leave us with 255 minutes of poker, or 17 levels.

5/10
10/20
15/30
25/50
40/80
60/120
80/160
15 minute break, color off T5 and T25
100/200
100/300
200/400
300/600
500/1000
800/1600
1200/2400
15 minute break, color off T100 and T500
2000/4000
3000/6000
5000/10000: should end here at the latest
10k/20k: if not, double the blinds to really end it!

If it still hasn't ended, split the payouts.

My 2 cents

I agree, just trying to contain the timeframe.

I have a no idea what the rebuy rate usually is for charity events. If it's 100% + an addon, that's 3 buyins per person. With the structure above it still aught to end around the same level. Otherwise, the super aggresive jump at level 18 should end things. So perhaps it works with unlimited rebuys anyway?

I would leave it to add-on only allowed at entry, so everyone would take it. Unlimited re-entries (slightly different than a rebuy), allowing the add-on multiple times. a 66%-100% increase blind structure will absorb the added players and rebuys, but takes a lot of chips, so that's why I need chip numbers. Any attempt to draw up a structure that the host cannot possibly manage is an exercise in futility.

I've helped run many of these charity events. We usually do unlimited rebuys during the rebuy period and an optional add-on for those who want it at the end of the rebuy period.

I every case we end up averaging 2.5 starting stacks per person. So that's a good number to use to estimate your total chips in play which can be used to determine your probable last level which in turn can help define your blind structure.

So in your case: 75 players * 2000 chips * 2.5 stacks = 375,000 chips in play
Using the 20 Big Blind rule the final level would be at 10k/20k.
You can work your way backwards from that to create an appropriate blind structure.

So I wasn't too far off, then! :D
