Does anyone know the average (median would be nice) number of rolls,
with contact, in a game? Actually, any summary of rolls-per-game
stats would be interesting, if nicely tabulated (Yes, I'm lazy).

I may be able to dig up about 10k-15k matches that I did dice studies on
from SHG. The matches were played among a wide variety of skill levels
and different match lengths. I had recorded every move into a database
and I might be able to do some relevant queries. I think I even had a
notation for contact/non-contact/bearoff.

One observation I will make is that I do know that the length of a game
will differ greatly based on the score. DMP games are generally longer
than earlier games that may end in Double/Drop.

Wasn't clear whether you were considering money sessions or match play.
The database I had was match play (3pts to 21 pts as I recall)

I'm sure that DMP games are longer, but quantifying that would
be interesting. I'm really just interested in a rough estimate
of how long games go before they become a pure race, and I doubt
that money and match play differ significantly, but quantifying
any discriminant would be interesting.

Thanks. So about 26 rolls per player per game. So
average rolls with contact is probably between 10
and 20 per player per game.

I think 10 is too little for the lower limit I would say around 15, but that's just my opinion a have no data to support it.

Sorry I didn't click this thread before. I did this study a long time ago and believe my results were 23 rolls was the length of the average money game.

I meant to post in this thread also but had never found
the time. Here is something I had posted 17 years ago,
for a different reason but on the very same subject,
that you may find useful/interesting.
