V1 and VR cannot be less than VMC. If you are using reduced power, VMC will be reduced to a lower number, which may allow a reduced critical field length. At higher gross weights, where VMC will always be less than Vstop or Vgo, I am confident that the critical field length is longer at reduced power.

I just ran the numbers for the C-130 and there were no weights that I saw the CFL at 970 TIT below the 1010 TIT numbers. However, they did get closer and closer the lighter I went. I did not go below the lowest practical takeoff weights.
Midas, if you want to play with the numbers, you can download a C-130 told calculator on the app store. The one with clouds is what the FE's on the 130 unofficially use.
