Which ruleset are you thinking of building your ship?

	- TNE (FF&S) and GURPS reverse the formula (install thrust quantity and
calculate thrust from the mass of the ship).

	- Most of the ship design sequences like HG use a formula which would make it
easy and obvious how to calculate a fractional drive system. T5 and MGT both use
a table, but reversing that into the formula isn't hard.
