Simply a list of engine ratings with each showing all tonnages (multiples of 5) of 'Mechs/Tracked Vehicles that can use them. For example, an engine rating of 100 can be used by 'Mechs/Tracked Vehicles of 10, 20, 25, 50 and 100 tons. If I have made a mistake or did not put in a weight, please let me know.
And before anyone asks, I did this out of boredom. Amusingly, the 10-ton BattleMech can theoretically take up to a 270 XXL engine, followed by the 15-tonner taking up to a 330 XXL, then the 20-tonner taking up to a 360 XXL.
An 'X' means no valid weights were found. Also, only doing up to the 400 rated engine. Maybe it the mood strikes, I'll do hover tanks or VTOLs next.
