load vs absolute load?

i have been trying to find the most MPG friendly way to accelerate and so i have been targeting 80% LOD at 2500rpm. however my LOD easily hits 99% or maximum during acceleration so i have found myself to actually be slowing down. this doesn't seem right, i thought 99% load means i'm going wide open throttle (getting all the torque car can provide at that rpm)? because certainly im not and im only giving about 1/4 throttle?! So someone helped me program absolute load gauge. Now this seems to be more relevant but i have also heard absolute load is not relevant to BSFC? during WOT absolute load maxes out at 95%. it's also usually 10-15% lower than load. it seems though that 75% absolute load actually means 3/4 throttle. so which one should i be monitoring?
