It's plenty strong for seated high-cadence sprints (max gearing, 90+rpm) , but seems to not be enough for the standing position for me.
The shortest intervals I have been able to do without getting tire slippage is around 30 seconds or so. Anything shorter than that and the acceleration is too much - I can feel the tire slipping on the drum. I can't imagine trying to do standing 20 second sprints.
To the OP, its possible you have a unit with unusually high resistance. I recently had to get a replacement resistance unit from Saris, and the power curve is dramatically higher than the original unit. Just a rough estimate is that 16mph on the new unit is the same power as about 21mph was on the old unit. I would not have believed 2 units of the same design could have been so different. Assuming they use the same impeller design and the fluid is the same viscosity, there should be very little power difference between 2 units with today's manufacturing tolerances. It may loosen up a little as the seals wear in, but it will never match the power curve of the original unit. So perhaps Saris has made some recent changes and you have a newer unit.
