Disagree ........... but then, that would be expected
You say he was 6 seconds behind with 13 laps to go for a rider somewhat renowned (some argue, the best exponent of) race strategy, tyre management, race management and with a need to beat the rider immediately in front of him for his championship.
I further (and totally) disagree with the respectable lap time part as the lap sheets clearly show that he was trying as he remained one of the fastest riders on track, just that he did not lower the lap times when he had a clear track.
Given that it is commonly accepted that dicing will increase lap times, it is also circumstantial (although many anectdotal and real time situation) would indicate that with clear track a rider can set and maintain a rhythym that is generally faster than the times when dicing. Ergo, if one cannot increase their lap times when they have clear track and their tyres are only 7 laps old (and ruling out a tyre issue), it would seem to support that the rider in question was not capable of faster lap times and if this is accepted,
was MM slowing VR?
Remember, that VR accused MM of deliberately slowing him down and yet the lap times (post incident) do not show that VR was capable of a faster pace.
The analogy and discussion is valid, just not so 'valid' given the manner in which the situation transpired in some eyes.
