Engine Movement bonuses

[Demorve]

Thy_Reaper, thanks for the formula you gave me. I was close to figuring out how the formulas worked in SEV, but with your help it put me over the top.

Here's what I finally decided to do. I changed the tech requirement for the next available engine tech to level 9 and then gave an extra movement bonus at level 10. In my opinion what this does is give you a choice: do I spend the extra research points to get the movement bonus with a large amount of supply storage, realizing that in the long run this is a temporary solution or do I spend less research points for the next engine class to get the movement bonus and start over with the supply storage?

When I tried adding the +1 at level 6, +2 at level 8 and +3 at level 10 I quickly realized that this method basically removed any incentive for researching above level 5 for the Contra-Terrene and Jacketed-Photon engines and since the goal was to make the upper levels of all the engine classes worth while to research I felt that this method wasn't any better than the stock game.
