Using canon as a basis is longer valid as they don't limit engine size by increments of the mech tonnage. Before a 100 ton mech at 100, 200, 300, and 400 as engine choices in canon/TT, right now you have 100-350 as engine choices. It's apples and oranges as much as one is inspired by the other.
Plus Speed Tweak giving that 10% boost has really thrown the ranges off. Most light mechs use to move 7-11 (fast for a light) would be at 118.8kph, now with speed boost going up to 150, we're giving mechs the equivalent of a 350 engine with only the costs of a 300 engine in weight and c-bills.
Before 120-140 kph was considered the ultra-fast range, now it's the lower end of acceptable in fast mechs. So any attempts at canon in MWO is an exercise in futility. Until they bring back limitations of engine sizes in increments of mech weight, the systems are forever different.
