Tournaments with both Howell and Mitchell movements
I am only qualified as a club director but I am mystified why in tournaments the director sets up room with both Mitchell and Howell movements for each session. Doesn't seem logical that the scoring reflects a true result when half are playing both directions and the other half only one direction. Can anyone explain why this is a regular happening these days? I can understand one session for all players playing Mitchell then the next session all playing Howell but a mixture of movements I fail to understand.

It does look a bit clunky but it is proper Duplicate Bridge
Which is where, on each board, every pair’s score is rated against the scores of all the other pairs who have the same cards.That those “other pairs” changes every round is not an issue
What would be an issue is if those “other pairs” are the same throughout and are collectively significantly stronger (or weaker) that the average standard of the field.
Mixing them up in this way helps avoid that - GILES HANCOCK16 Aug 2021 at 06:45PM
I've done it sometimes because I think it's a better movement.
e.g. 20 tables
Could play a Web, but nicer to play a 13 Mitchell and a 7 Howell, creates different sets of comparisons.

And if Giles was to run 3 sessions with that format (a long day - 39 rounds
) it would have everybody plays everybody exactly once
Which is "ideal" - GILES HANCOCK17 Aug 2021 at 05:03PM
Yes, maybe for a 10A. 78 boards.
It doesn't actually produce the perfection of all-play-all, there is one extra pair in the Howell.
