"You see the problem? Using standard moves increases performance too much! It also limits the variety of speeds available!"

You can negate this effect by using larger numbers..

Ship with 4 engines per move, standard engine gives 3 move
1 engine: 0
2 engines: 1
3 engines: 2
4 engines: 3

Level 2 engine, 4 move
1 engine:1
2 engines: 2
3 engines: 3
4 engines: 4

Look at P&N for more examples. Just as an FYI..
