I saw something odd... i recalculated it a lot of time, but cant figure it out.
This problem effects Bookbinder, Barrack and Provision House, but for explaining i take the Bookbinder.
When a bookbinder is lvl 3, it takes 28 hours to make a codex.
When a bookbinder is lvl 4, it takes 21 hours to make a codex.
But when you'r going to upgrade the bookbinder from lvl 3 to lvl 4, it say: increase production speed by 33%.
But when i calculate it, 33% faster then 28 hours, should be less than 19 hours, not 21 hours. Am i a noob in calculating of is this really wrong?
This is all the same with upgrading to other lvls.
Who can explain this?
