I’m surprised that no one has commented on the sled pulls with a relatively large performance decrement (.6 difference between the two). Definitely not within the accepted 10% dropoff range. At this point does the purpose and effect of the exercise change?

As an aside I also saw a picture with Bolt pulling a sled loaded with the same amount that Franno prescribes…

I always timed sleds over 30m so the difference may be alot less.
Starting from zero is more resistive than entering the final 10m segment (20m to 30m) at a high speed. So 10% to 30m would be higher difference 0 to 20 and higher still 0 to 10.
As for the poundage, all that really counts is the surface friction created- that’s where the resistance comes from.
