Player can change the Pool EV formula for GGpoker
The option is availbe only before the period starts and can be applied only for the whole month. If you don’t change the formula, your previous choice will be autoprolongated for the next month. You are not able to change it during the current pool period.
Let’s compare the formulas which are available.
By multipliers (MultEV)
- Eliminates the variance of all-ins
- Does not reduce the multiplier variance
- Does not underestimate the EV
- Losing high multipliers to maintain PVI is allowed because it means a loss of similar EV
This formula is based on treating every single tournament as a separate Sit&Go with a set prize structure. ChipEV and multiplier of every tournament will determine this tournament`s EV. Total EV is a sum of all EVs.
By multipliers, x50-x100 merged (MultEV50)
- Eliminates the variance of all-ins
- Reduces the variance of multipliers х50 and x100
- Does not underestimate the EV
- Losing high multipliers to maintain PVI is allowed
The formula is very similar to the MultEV formula, but x50-x100 are effectively merged into a single x66,66 multiplier.
By average stack and average multiplier (AverageEV)
- Eliminates the variance of all-ins
- Reduces the multipliers variance
- Underestimates EV for 12-14 buy-ins per 10k tourneys
- Losing high multipliers on purpose to maintain PVI is considered as a pool scam
This formula is based on calculating an average stack & cEV & multiplier of all tourneys, then calculating EV of all of them.
When comparing the formulas, it’s important to focus on the following parameters:
- *EV loss*
- *EV volatility*
To estimate these parameters for different formulas, we ran a 100M tournaments simulation – 10k runs of 10k tournaments. The results were as follows:
MultEV has the highest EV, but it’s Std Dev is 38% higher than AverageEV;
MultEV50 has slightly smaller StdDev than MultEV. Difference in EV is caused purely by variance, in reality EVs are equal (assuming same cEV in x50 and x100);
AverageEV loses roughly 13BI/10k tourneys, but it’s the least volatile formula
X axis - EV in BI over 10k tournaments
Y axis - chance of getting it
So if we look at some point on a red graph, say, A(-350; 6), its coordinates would tell us that there’s a 6% chance of getting roughly -350 EV over 10k tournaments while using AvgEV formula. This graph illustrates that AvgEV's results are noticeably more consolidated (meaning less variance), but they are lower on average than MultEV`s results.
The following effects should also be noted:
On average ~58% players will have their MultEV > AvgEV over 10k tournaments. The difference in formulas EV looks like this:
The blue line shows the point where the difference between the formulas is zero.
Position of the player in distribution will largely depend on how many x50-x100 he hits and how he performs in mid-to-high multipliers, like x10+ or x5+.
On average MultEV > AvgEV, but it is possible to get very few x5+ or run very poorly in them, thus ending up with AvgEV > MultEV by a wide margin.
