[r-t] Re: 76 spliced surprise and 4ths place delight

[John Warboys]

PJE requested a commentary so here goes.

The approach I took for this was the same as my 5040's for the 41 Surprise
(No's 1-5) and the 42 3rds Place Delight, i.e. to build up a group of grid
splices which incorporate all of the required methods.  Each grid splice is
split across different 'extents' and different backworks.  The 76 is put
together using 6 different grids (A-F) as outlined below, all with the 6th
as observation.  I then added an extent of Old Oxford with a couple of
courses course-spliced as Marple.  These base courses, along with
traditional splices, can then be arranged to include all 76 methods.  When
I put this together (2 or 3 years ago now) I only managed to find one other
set of grids which would allow inclusion of all the methods, but there may
of course be others that I didn't find.
