Yes. Assuming that a significant number of perturbations could be applied to
make sufficiently different from Stedman.

Yes - I agree. Currently, the longest Triples plain course is Upham
Differential which has a 70 change lead x3x4 giving an 840 change course. It
does benefit from having distinctive features in the blue line which I am
sure must have made it more memorable for the band, whereas I have always
thought Scientific's line to be rather short of interesting features.

Upham has been mentioned by Philip before, saying that RAS had found many
similar differentials.  Did he look for ones with longer leads though?
