I am not sure how this is "cute", this is how TSP is defined and used- specifically that it is ANY MEASURE to reactively speed up transit, there is no minimum % of speed up required to be called TSP. This is precisely why its used less often in favour of more explicit terms like absolute TSP or strong TSP, where ATSP more accurately decribes "no LRT is ever, never held back by a red traffic signal or an advanced left turn signal"
You are free to tack on your minimum requirements on the definition of TSP, but you are going to start talking past others.
