Hi all,

I'm really tired for playing match points mitchell movements.
All that is played here is played in that format.

Where could i find some information about different tournament and scoring systems?

I read about a pairs tournament (usa trials?) playing like a match where table B was the field with/without top & bottom.

What is SCRAMBLE-MITCHEL?

Any has information about or knows where i could get it?

What do you think it could work best if you want a tournament with:

-30 or 40 sessions.
-General individual scoring
- Not all the pairs playing all the sessions
- Not all the players playing all the session
- Not al the pairs playing always together
- You have more pairs than tables for each session.

Thank you.

We would call something like that a rating system (which does not invalidate it).
Perhaps it is really only quite similar to a rating system since such ratings would start from scratch at the beginning.

Typical components needed to compute a score (rating) would be:
Accumulator and counter - the parts whose quotient is the rating (the counter might count comparisons or boards depending on how you wish results from small sessions to relate to results from large sessions).
Predictor formula - may be based on current ratings or not (maybe just predicts 50% or 0 Imps depending on scoring pref)
Corrector formula - determines the amount of adjustement to the accumulator for each comparison/board (can be either a simple linear adjustement or something more complicated like a moving average which would count later results more significantly than early results).

Simplest cases result in average MP/IMP per comparison/board with a qualifying cutoff. Of course, if a player actually plays strictly with a single partner then they will each end up with identical scores. Under the conditions given, this might lead to a form of abuse where pairs that do well early end up bidding for the best pro ringers for the run to the wire. This is simply one of the defects of rating systems.
