Improved Economy, Breaks the bank ... Options

[Westiex]

So I was looking at the Ares Kull (P120 Arsenal) and was looking to get the Improved Economy mod done to it.

Relevant stats
Accel (running ) is 150
Speed is 300
Base cost of the drone is 10K (IMG:style_emoticons/default/nuyen.gif)

For improved economy, the cost is Accel (running) x Speed x 5

So to get the mod applied to the drone, I'm looking at paying 225 000 (IMG:style_emoticons/default/nuyen.gif) ?!?

Even appling the max 'Walking' speed instead of running the cost is still 45000 (IMG:style_emoticons/default/nuyen.gif)

Going away from the kull for a moment, I'll do the example on a Dodge Scoot
Accell running is 15
Speed is 60
Cost is 4500 (IMG:style_emoticons/default/nuyen.gif) for a 3000 (IMG:style_emoticons/default/nuyen.gif) scooter.

Harley Davidson Scorpion
Accell running is 30
Speed is 120
Cost is 18000 (IMG:style_emoticons/default/nuyen.gif)

I'm just wondering if these numbers seem right to anyone who knows about these sorts of things RL?
