Remember that your total reaction vector from your rotor disc has two components in forward flight :
The first is a vertical component, and is what holds you up in the sky.
The second is the horizontal component, which pulls you forward (or backward or whatever.)
When you are very heavy, most of the torque is used just to keep you up. Tilt it too far forward, and you will start to sink, so you will be limited on how fast you can go. Similarly, for the same torque figure, you will be going slower when you are heavy.
A Jet Banger in normal cruise is around 70-75% Tq to get around 100kt. To go faster, or if you are heavier, you will use more torque.
But it is unlikely that, once you are into the drag bucket above 30 kt, you will be pulling over 85% just to stay airborne. If that was the case, you would be pulling 200% just to hover.
85% cruise will move you quickly, but at the expense of fuel burn. Also watch your TOT limit.
