Alright, here goes. Simple excel table showing prices for all 3 tiers.
I strongly recommend to download the table because in google docs view filtering does not work properly.
This is link for leveling.
Either you can filter span, so how much DNA and time is it gonna cost to get from one level to another or you can check individual level in the table below (filtering levels is also possible). Dont forget to set discounts for time and costs according to guild level.
At the very bottom is total count - so how much does it cost to level unit from lvl 1 to 50. Sometime table shows some nasty numbers
