Robert bets the mods the Mariners will be average - update


September of last year, our intrepid hero made the following bet - if the Mariners are within five games of .500 at the conclusion of play, August 31, 2009, he becomes a mod for the month of September. If the Mariners fall outside this nine-game window, each mod gets to cockpunch him at a time and location of their choosing.

Just today, new user Poochie asked for an update on the status of the bet.

I've created a simple WE chart for the bet, based on a simple binomial distribution, and assuming the Mariner's current Pythagorean Expectation to be their odds of winning the next game. After that, it was a simple matter (well with a lot of numbers) to determine the approximate odds of the Mariners winning between 64 and 69 games before September 1

After tonight's game against the Orioles, the M's have a Pythagorean expectation of .442 from here on out, and they've won 25 games already. Thus, I simply needed to find the probability of them winning between 38 and 43 of the next 80 games. As you can see, the odds aren't bad - about 40%.

I repeated this process retroactively for the beginning of the season - as you can see, the team was much too good to hover around .500 at the start of the year. Ironically, the high point of the graph came on Silva's last start - it's been all downhill from there.

EDIT: Updated through tonight's 3-2 victory over Baltimore - Robert checking in at a robust 26.4% chance to avoid three junkpunches

Well this is entertaining

and says a lot about its creator

But aren't you a new user?

I don't know how to stop.

Amazing how you get these wrong so often.

Of course I’m kidding. As JI well knows, given the goofy trolling incident from last week.

I don't know how to stop.

This, incidentally is why I can't use deadpan around here.

Too much flat-footed sincerity and everyone starts assuming that you’re never cracking wise at all.

I don't know how to stop.

JI used to be butthol, there's no way he's poochie.

Besides lets just pretend you’re right, then how do you fit fogel into the picture. Sheesh

Fogel and Robert are the same person.

A vote for everyone is a vote for you

since you are, by definition, including in “everyone”

by seattlebruin on Jun 3, 2009 9:16 AM PDT up reply actions   0 recs

I voted for you

Those of the glorious first name must stick together

by rlintott on Jun 3, 2009 9:42 AM PDT up reply actions   0 recs

I did.

As pointed out, “everyone” includes “Robert”.

Where did LFOJL go, anyway?

Sometimes it almost seems like he’s still here, haunting us in another guise.

In hindsight, my numbers are wrong - Robert in fact needs the Mariners to accomplish one of the six following records in order to win

64-69
65-68
66-67
67-66
68-65
69-64

With 25 wins, the Mariners must thus win between 39 and 44 games remaining – this leave Robert just a .5% chance of actual success, unfortunately.

Buh?

Those numbers look completely wrong.

by Matthew on Jun 3, 2009 1:21 PM PDT up reply actions   0 recs

Oh no, wait, my correction is right

my original calculation is based on the M’s winning between 62 and 71 of their original 133 games (clearly wrong, I just took [133/2] +/- 5), looks like I just summed the wrong row to get the .5% figure. according to my spreadsheet, it’s actually like 22%, which makes sense given that I had 62-71 wins at .389.

"Each mod gets to cockpunch him at a time and location of their choosing."

I am going to wait until the fateful day that Robert gets married.

by Graham on Jun 3, 2009 2:53 PM PDT reply actions   3 recs

This doesn't seem that unlikely.

Except perhaps the Robert married part.

by NOLAmarinergirl on Jun 3, 2009 4:39 PM PDT up reply actions   0 recs

Well this tops any of my practical joke stories by a country mile

I do appreciate you not dropping this story right off the bat however.

by Kermit. on Jun 3, 2009 4:04 PM PDT up reply actions   0 recs

I am so glad I don't have nuts.

I would live in fear of seeing you outside my window with the BK mask on, ready to deliver some sort of testicle pain.

by royalcurve on Jun 3, 2009 5:04 PM PDT up reply actions   0 recs

That wouldn't explain it at all.

There had to have been some point in which we were expected to finish around .500

by Graham on Jun 4, 2009 9:30 AM PDT up reply actions   0 recs

Especially since our run differential had to have crossed over from positive to negative at some point.

Given the fairly wide range of potential Robert-favorable outcomes, a binomial distribution based off of an even run differential should have given him a fairly good chance somewhere around when the M’s cooled down.

by abender20 on Jun 4, 2009 9:38 AM PDT up reply actions   0 recs

Robert picked a very specific 5-game stretch

out of 134 possible outcomes from the start of the year, only 6 are winners for Robert, and even though they’re the most likely 6, about 45% max sounds right to me

by seattlebruin on Jun 4, 2009 9:50 AM PDT up reply actions   0 recs

6

I thought it was 11 at first too, by doing [133/2] +/- 5 but look in the above subthread

The only winning combinations are
64-69
65-68
66-67
67-66
68-65
69-64

63-70, 70-63 would each be seven games below/above .500, and thus losing combinations for Robert

by seattlebruin on Jun 4, 2009 9:57 AM PDT up reply actions   0 recs

It depends on how you define "within five games of .500"

A team that finishes 76-86 is ten games under .500, but within five games of a team that finishes 81-81.

by justcougit on Jun 4, 2009 11:36 AM PDT up reply actions   0 recs

The other thing that hurt his chances a lot was that our run differential

got to ~even by getting blown out a lot, so even though our run differential got to around 1:1 quickly, it also came with a lot of losses, decreasing the chances, meaning the M’s would need to play over .500 ball with a negative run differential

I just looked at this for the first time.

This dude is so getting cockpunched.
