Very cool!
How about adding in the DLC ships?
And adding a column for the speed stat for each ship to the chart?
And sorting it by Top Speed?
And adding a column for percentage of top speed gain increase with pitch?

I think the most interesting thing learned here is that the speed gain appears to be a constant regardless of ship. So slower ships are seeing a slightly larger benefit (they get a larger percentage increase in top speed) than the faster ships.

It's very also good to see that in true WO fashion the difference between "best" and "worst" is very small, a piddling 9 Kph in this case.

Good study!
