It seems worthless to expand the longitudinal accuracy of the projection as

The useful range for the tmerc is in the immediate vicinity of the central 
meridian so why bother worrying about extending computational accuracy in the 
longitudinal direction?

Do you have a better suggestion if you need a single projection over a broad area?

Didn't think so.

Enough is enough. Please.
