Re: [hr100] Re: Odds?
- Here are the odds I calculate by running a million monte carlo lotteries for the "never-started" lottery. I'll calculate the others soon.
I've left out some of the in-between numbers.

- Oh, I most definitely agree Fred! Very fun, great social atmosphere, and the work is most gratifying.
I'm making some assumptions here, but I find it logical that the reason why extra tickets are given out for Hardrock-specific trail work (or aid station captaining, etc) is to incentive-ize folks to volunteer specifically for Hardrock itself. I can find almost the same gratification by volunteering for more local trail workdays or events.
Of course I'll be going to Hardrock to volunteer regardless of what extra tickets I earn or don't earn, because of its great character, environment and the opportunity to learn more of the terrain for when I do get in, but its a lot easier to justify a 700 mile round trip to both the wallet and fiance (or by Hardrock, wife :) when the service tickets make a (more) meaningful difference.
Michael Bur validly pointed out that any difference in the weight of service tickets across the lotteries could very well be an intentional choice on the part of the race committee to weigh factors more heavily in favor of the "the poor sap who keeps applying but keeps losing out," which makes good sense, if that is the intent. I was initially working from the assumption that the race board would want equality of value of service tickets across the lotteries, but perhaps I could very easily be wrong.
As Mark Oveson said, "the motivation for Never Starters has now shifted almost entirely to making sure you stay qualified and apply every single year. Trail work is only marginally helpful."
Right now, it's a lot more than marginally helpful to those who are first or second time entries in the lottery, as one service ticket increases the odds by roughly 87% & 40%, respectively, since the odds for those folks is so much smaller to begin with. But those who are in their third year or beyond of applying get, at most, a 17% bump in their chances. Changing from [(2^N) + S] to [2^(N+S)] seems to make the bump from service tickets more equal across the Never Starter lottery, but is that a desired goal?
I guess the main question is: Does the reason that the service ticket incentive is offered imply a goal of having that incentive be of equal value to all interested parties across the board? And if so, is that equal value goal being accomplished in the current formula?
Anyone up for a nice long run this Saturday where we can discuss this in a better format than email? :) (Seriously - I'll be going for ~35mi, starting at 6:30a at the Apex trailhead in Golden, CO, but the route has options to cut it to ~14 or ~25.)
