56 opens * 15G/open = 840G. We got 5 days, so I'll assume the average CC addict can comfortably get 48 opens in with a clock hour between them, so we'll assume 8 resets for 960 total.

Note: 5days*24opens/day=120 opens, so if you didn't sleep and started the event as soon as it was opened, you still would need gold resets at >=80% chance.

PS Since I assumed 48 free opens, just add 47*15=705G to the totals above for the "first" crowd.

Cool analysis. I didn't check the math, but this is useful stuff.

[OneHoop]

I did it by calculator, not spreadsheet so checking the math might be useful. If nothing else, it gives you an idea of how many boxes (kegs) to save for overtime.

Wait a minute. You mean I can't improve my odds if I wait 30 seconds, wave my phone around in the air 3 times, and tap very slowly? Let me know right quick because I might have to change my strategy.

(Good stuff with the tables. Thanks)

Math:
1-(1-SUCCESS)^TRIES=LIKELIHOOD
(1-SUCCESS)^TRIES=(1-LIKELIHOOD)

TRIES= log(1-SUCCESS) / log(1-LIKELIHOOD)
[NOTE: can substitute natural log, ln, for log]

eg, if LIKELIHOOD=2%, SUCCESS=67%
TRIES = log(0.33)/log(0.98)
TRIES = 54.877
Ergo, need 55 successful opens from beer #9 to have a 67% chance of beer #10.
Check: 1-(1-2%)^54.877=1-0.98^54.877=1-0.33=0.67.
or 1-0.98^55=67.08%

I think it is Tommy Two Toes who posited that cash opens are about 33% successful, so you can roughly multiply that by 3.

That's honestly the only part that is speculation. For my calculations I use 35%, but I feel like that's really much lower than it is :/ Maybe more at 40%...

Well, we could do a comprehensive study but it's probably not worth it. Even combing through the tracking threads should converge on a good approximation.

My simulations point towards a rate between 35% and 40%, but then again they're seeded a little differently than an open per hour over the course of a week. That is, if they do use just a simple random algorithm. I think they'd at this point be using some sort of predictable system so they can check the legitimacy of results.

[mxz]

Why are you simulating it?

sum(special items,cash,RP, bikes/batons/other useless items)/# opens

The problem is we don't know how well/accurately people record their opens.

Agreed. I based my hypothesis on a really small sample. (Maybe 120 open attempts).

As the contest went on, I think it improved slightly

Last time I calculated, I had 62 attempts on each of 3 accounts for a sample size of 186 (still very small). 111 BLNTs for an open rate of about 40%.

[bald zeemer]

So all the guys who got caned for 5-6k gold in their first-open attempts were getting normal open rates, it seems. I'm not sure how much solace that will bring, but it's interesting to know.

[OneHoop]

Lots of people dropping gold for 30% off building upgrades!

We don't actually know the odds are the same this time, but lets assume they are and look at the special situation where you've managed to get 9 paper bonds for free and want to spend gold to get lucky number 10!

I'm going to stop here, because most people aren't being persuaded by math in this but also because it is already obvious that you are not increasing your probability of winning by 2% every time you open one. (eg, chances only go up by 0.76% between 49 opens and 50 opens) It's not additive--randomness doesn't care how many times you lost already. Although, you'd probably have a whole garage full of enhanced bikes if you got to that point! ;)

Good Luck---or should I say Gold?!?

Any computer scientists out there to chip in about how RNG's aren't really random and how that would affect this analysis?

Not without knowing what type of PRG they use and how it's seeded.

Edit: and if they did use a PRG I can almost certainly say it wouldn't affect the probabilities, but that's based on the assumption that there are no other hidden factors at play (e.g. not saying this is at all the case, but for example something like top gold spenders are given better odds, etc). I feel like there are, but I don't know what.

Edit 2: if you knew how the PRG was seeded (typically computers use something like the computer's time converted into milliseconds), and how the seed affected the outcome, you could guarantee a successful "drop" each time. Though that's obviously not going to happen.

Wait, so it really will help to "wait 30 seconds, wave my phone around in the air 3 times, and tap very slowly"???
::grin:: (you would have to be able to sync to the server computer's clock and account for network lag)

re: Edit 1: Occam's Razor almost always applies to computer programs--the easiest explanation is the most rational. This is because programmers will almost always reuse subroutines and variables when they can. I don't think that it is any more complex than they had to make it to maximize revenue.

So that's what I'm doing wrong. I was waiting 3 seconds, then waving the phone 30 times. <SMH> So silly of me:D
