A form of pairs scoring defined by BBO's RMB on the MrBridge Site
Strategy and tactics are the same as for IMPs. Given the datum (average of aggregate scores -- sometimes adjusted), each pair can easily compute/check their own IMP score on that board.

FWIW, I prefer Butler scoring against a Bastille (continuous) IMP scale, using a datum that makes the IMP scores sum to zero.

You can find past threads discussing issues of Butler scoring, including the merits of Butler IMPs versus Cross-IMPs:

In this age of computer scoring, Butler events are becoming rare. Cross-IMPs are more usual now. In this form of scoring, no scores are thrown out and no datum is computed; your score is simply compares with that of each other pair in your direction.

And we are grateful for that. I so look forward to the day I no longer hear the "d" word - especially the day I no longer hear it said from old A player to newer IMP pairs player who shouldn't really start off misinformed (even though to them it doesn't really much matter, but then again, details of "compare-to-datum" shouldn't matter either).
