I think the athlete perceived it to be slower as they expected they would be working harder with the increase in reps and the need to accelerate twice as often (as opposed to 5 in the standard session). Although with the rolling start the effort to get up to speed was probably not as significant.
I will try and monitor the next session when this is done and then decide on the adjustments to be made (last session times were recorded by the athletes friend as i was away with work), it may be that the accuracy of times or commitment on the runs were not where they should be - my initial thoughts with this session were that the athlete should be running the reps at about 12.5-12.6, given the rolling start and their current conditioning level i wouldn't have expected them to have a large range (actual times ranged from 12.2-13.1, averaged to 12.75)
Whats your event and PB? Completing 10x100m @12.75 (+ or -.25) off 60s recovery means you have a highly trained glycolytic energy system.

It is reasonable to assume that an athlete capable of such a performance is able to run 100m from a rolling start in 11.0 seconds in a single set of 10 reps with appropriate recovery. As much fast relaxed running at a pace aound or quicker than 12.25 per 100m, particularly in a climate of endurance development would seem to me to offer enormous benefits to the one lap sprinter.
The optimum range for Intensive Tempo work is around 85-90% effort. This range equates to between 12.95 (85%) and 12.22 (90%) for 100m reps.
Duration of recovery will depend on the training status of the athlete(s) concerned.
I prefer experienced athletes to take 60 seconds recovery per 100m worked in such situations, but I think DMA's suggestion of extending this (my own suggestion would be 75 sec per 100m worked) has good foundation, particularly in developing athletes, depending on their level of maturation.
If you are using grass to work on, however, (you didn't specify) I would say your 12.75 target is a good one.
The primary focus of all Intensive Tempo work should, of course, be on a sound technical model.

Just to clarify after making a pig's ear of my intended meaning in the above paragraph:

I should have said that, s/he would be expected to run 11 sec from roll IN A SINGLE REP - thereby achieving a time on which to base the 85-90% effort (12.25) in a 10x 100m set, with appropriate recovery. If only my athletes were as quick on the track as they are to highlight my pc deficiencies!
