Horizons Shield % reported in right panel not same as Math of units

[RoninCahill]

I noticed FD added a feature to the right panel to see the shield level and resistances. It is however reporting the thermal/kinetic etc. values as less than what is actually added up. I added the shield (thermal for example) % plus the total of all the shield boosters (thermal) % and that total was 43% however the right panel reported it as 31.7. is there a hidden thermal % reduction at work to make all my values less or is there a different Math calculation to the stacking of multiple boosters at play.

this isn't really changing how nifty my shields are but I am curious.

Thx

It's multiplicative, not additive, and beyond 50% there is a further correction.

Two 15% resistance boosters is not 30% resistance, it's ~27.7 (.85 * .85), and three isn't 45%, it's ~38.6%.

being a math teacher my interest has been sparked. do you have all the specifics around this including the exact correction amounts?
