I'm afraid I'm somewhere at the other end of the spectrum; for example, when I used Vehicles I would get out my calculator and find the exact cube roots instead of using the table, because it was faster and easier. Then there was the time when I'd mislaid my calculator and got out one of my slide rules (I keep two as ceremonial heirlooms) to approximate the cube roots. . . .

When I was working on Weird War II, though, I put in a table of multiples of exhaust velocity you could get as final velocity based on percentage of mass that was fuel/reaction mass, to spare people taking logarithms. If Spaceships has done the same thing I think that's a good idea.
