University Research discount help

[Mountainking]

Can anybody tell me how does the university discount bonus from mansa musa, hiawatha and atomium works? I tried 2 formulas but it's still way off.


FORMULA 1: First one 60%+10% on base time it takes to research

	Research name	Original days	60% discount mansa	70% Discount with Atomium
Lvl1	Wall & Gate Hitpoints	4	1.6	1.2
Lvl2	Wall & Gate Hitpoints	5	2	1.5
Lvl3	Wall & Gate Hitpoints	6	2.4	1.8
Lvl4	Wall & Gate Hitpoints	7	2.8	2.1
Lvl5	Wall & Gate Hitpoints	8	3.2	2.4
Lvl6	Wall & Gate Hitpoints	9	3.6	2.7
Lvl7	Wall & Gate Hitpoints	10	4	3
Lvl8	Wall & Gate Hitpoints	11	4.4	3.3
Lvl9	Wall & Gate Hitpoints	12	4.8	3.6
Lvl10	Wall & Gate Hitpoints	13	5.2	3.9

FORMULA 2: Apply the percentage on the decreasing base each % bonus would give that is 3% 20 times and then 10% atomium

Isn't Gold Skill Research Cost only 30% max? There's two researches at 3% per level with 5 levels each.

I thought it was 60% somehow :facepalm:
Thanks Cannibals

My level 8 research shows 7d16h, which is correctly a 30% discount off of 11d base time. I don’t have atomium.

Just curious, have you finished polymath from leonardo?

 

[pckrn]

your calculation is wrong because you're discounting from a discounted price.

lvl7 wall and gate is originally 10 days.

3% discount is 0.3d so after one discount it is 9.7 days.

but after this, for the second discount you calculated 3% of 9.7 to get .291d instead of 3% of 10 days which is still 0.3d

every step discounts 3% of the original price so 30% discount of 10d is 7d.

with atomium you get 40% discount from 10d to get 6d
