For example
data.raw["mining-drill"]["cursed-drill-999"].mining_speed = 149.85
data.raw.turret["cursed-turret-891"].name = "cursed-turret-891"

Why not exponential progression, where every step is twice or 10 times higher than one before?

I've tested difference between 100 and 5k (On every entity) and i don't feed a significant difference loading...

You sugest have 100 entities where require x100 experience each level? But i like to see the advance.
I don't take 3 hs for evolve a entity from 50 to 51...

I don't like those games where you have 10 lvl where lvl 1 is weak and lvl 10 is very overpower... Don't have sense to me.

It can be just a little big higher, for example with factor 10^(0.1) so every 10 tiers will be 10 times more.
The formula looks like: y=(10^0.1)^x

https://www.google.com/search?q=y%3D%2810%5E0.1%29%5Ex

So 10^0.1 makes next tier only 25% more difficult, it's around 1.2589254117941672104239541063958

And that's the formula for what?
At lvl 30 you have 1.000 what? and 40 = 10.000, and 100 = 10.000.000.000 (10G)?
Of mining speed? Experience required for next lvl?

Yes, next level needs 25% more experience than previous one and gives bonus exactly the same 25% more than previous level.

Update
So if you divide the needed time to received bonus then you get that same as by your mod, but in less amount of levels.

For a entity lvl 1000 you need exactly 8.272.662.454.689,12 of flesh. (Because every 100 lvl you get 70% less of experience)
But every 20 T3 talent of respective entity, your flesh gives 5% more of experience, at lvl 100k you need only 1.654.201.651 flesh for a full entity

NOTE: I think level 1000 is ridiculous, the speed of everything, it's not something that you should try to reach.
