Moreover, using 'xxx=figure" breaks simple "cut" pipelining to extract the
figures, so I would prefer to stick to spaces.

Maybe:

  progress: 36.0 s, 115.2 tps, lat avg 9.678 ms stddev 1.792, lag 0.143 ms

but I liked my "+-" approach:-)

100 +- 3 implies a range of 97 to 103 and no values are outside of that
range.

This is one of the possible meaning, but ISTM that it is not exclusive. Anyway here we do not have a symmetric distribution of run times.

Well, it seems I'm alone in liking my +-, so I'll backtrack on that.
