Alright, I'll add two cents, only thanks to having slept in a Holiday Inn last night.
Much of the discussion about maps has centered around the Touring model as Triumph chose a high torque "down low" - less power high bias. So for the Touring owners, there is much more untapped potential and thus easier to notice a seat- of- the-pants difference without paying too much attention.
For the Roadster, my sense is the mental calculation is different. The potential gain is less, and easier in a relative sense to mess things up than improve.
For the Roadster, it probably makes sense to make the extra effort to find a competent dynamometer and seek incremental changes based on actual measurements.
