AlexTrebbert, SwC is aware that you and others want the rake adjusted and find ACR's higher % but lower max rake to be more favorable. They are currently working on creating a new rake schedule, which should come out this week.
Like others have said: The cap is really the only thing that matters, the % is basically irrelevant.
I think you should consider coming up with a plan now on how you intend to respond to future price changes in bitcoin. If the price of bitcoin goes down, the cap should go up, and if price goes up, cap goes down. Informing players ahead of time what price will trigger the change, and what the change will be will avoid having to go through this in the future.
The % is relevant. SWC made massive changes to the rake percentages a few months ago.
Let's look at the micros. The cap is rarely hit in the micros in NL or limit poker. So the % is the most important thing. Even if you adjust the cap to something hypothetical like 27 cents usd in the micros which is approximately 10 swc chips. When the % was 2.5% you would need to hit 400 chips to hit the cap. Now with current 3% rake you would need to hit 333.33 chips to hit the cap. At $27000 BTC price, a 400 chips pot is $10.80. Take a look at what is currently running on SWC below
The only games running right now are micros. The average pot size on both of these tables are below the rake cap. 203.93 average at 5/10 and 190.53 at 2/4. So on average the % is in play. And if you scroll up you will see that SWC increased the rake percentage by 40% on these tables 4 months ago. I'm sure the cap is hit occasionally at the tables listed above so this doesn't equate to an flat 40% increase, but it is very substantial nonetheless.
You will also notice that the rake caps in limit poker are substantially higher when 6 handed than heads up. This is completely standard and acceptable. So the % at say a $10/$20 mixed game will come into play at a full table very often. Lets hypothetically give the this $10/$20 game a $3 USD rake cap. The % was 1.5% earlier this year at this table, now it is 2%. $3 USD is 111 SWC chips at $27000 BTC price. At 2% rake you need a 5,550 chip pot ($150 USD) to hit the max. At 1.5% rake you need a 7,400 chip pot ($200 USD) to hit the max. At 300/600 11 game mix ($8/$16 stakes at $27,000 BTC), let's examine a 6 handed game where it is folded to the small blind who raises a limit holdem hand and proceeds to bet every street, getting called by the big blind each time. Small blind is 150 chips, BB 300. So 1200 pre, plus 600 flop, plus 1200 turn, plus 1200 river = 4200 chips total. 4200 chips = $113.40. Rake cap is not hit. The additional .5% = 21 chips = .56 cents of additional rake.
