23456 M W H 54362 s s s 65423 3* s s 24356 s - s 65432 - s - Repeat. Fourth place calls. 3* = s - s. Some bands may prefer the reverse: 23456 M W H 34562 s 3* s 56423 s s - 24365 s - s 65432 - s s Repeat. Fourth place calls. 3* = s - s.
Either arrangement contains 94 little bell rollups at the back, including 20 each 23456s and 65432s; and 82 little bell rollups at the front.
However, the unreversed version contains more of the little bell rollups at backstroke, and also contains more near misses.
Either arrangement is true to all (in course) CDFL1L2ORU2 and (out of course) HN2Tbc.
Warning: not all the work.
