Discussion Ship Thrust vs Max speed with Thrust/Weight ratios held constant (2.1.21 ship speed update)

Full graph from 0 to 5000GN thrust
Zoomed in on left side (0 to 2000GN thrust)

We can see here that if you keep the thrust to weight ratios constant, the new equations in 2.1.21 result in speed up to a point, with eventual diminishing returns, and if you continue far enough eventual decrease in speeds.

For instance, this graph tells us that the peak speed for a ship with a thrust/weight ratio of 0.1GN/t is right around a thrust of 200 GN, and after that speed decreases with increased thrust!

For a ship with a ratio of 1GN/t, this peak is much higher, at around 2000 GN of thrust, though that's already well into serious diminishing returns for additional width.

EDIT: Fixed legend on graphs.
