Rng  ECM GHzd  effort/factor  Wh/factor
2M  0.0845 GHzd  84.5 GHzd  8,450
4M  0.180 GHzd  180 GHzd  18,000
6M  0.270 GHzd  270 GHzd  27,000
8M  0.397 GHzd  397 GHzd  39,700

Given the amount of P1 and TF already done for those numbers, I think it is advisable to run ECM curves with B1 = 250000, B2 = 25E6.
