[r-t] Double Treble-Bob Maximus Methods

There are not many existing regular double treble dodging maximus methods 
- I count 25, of which 7 are lead-head code m.

One existing method, Redland Surprise Maximus 
https://complib.org/method/22908 could be a good method for generating 
runs, as being a double method with lead-head code m it has repeating 
leads with calls at the lead-end or half-lead, and with plain hunting or 
dodging on six bells at a time can generate 6-bell runs quite well.

This is one way of exploiting it:


5040 Redland Surprise Maximus
Composed by Andrew Johnson
23456 O     W     H
24536       –     –s––s
54326 hhghh     2     ––s––
25346 hhgh  –     ––s––
42356 hhgh  –     s
32456 h           s
23456 hh          s
h = 9T HL Bob; g = 90ET HL Single.
12 56s (0f,12b), 24 65s (0f,24b), 542 4-bell runs (257f,285b), Backrounds.

Brian's "Pleasant Surprise Maximus" isn't quite as good for this 
composition according to the CompLib score, but has better counts of the 
runs except for 5-bell and 6-bell runs. A rotation might give a better 

Another composition for an m lead-head code double method is

5040 Avon Delight Maximus
Composed by David G Hull

which uses the same types of call, but exploits the hunting on 8 in Avon 
to generate more long runs.
