Topic: The issue with module stacking -How to fix with Penalties.
Take the old pre-patch Riv Mk2 t4 tunings from wiki:
First tuning => 121 x 1.1 +10 = 143.1 % (mining amount/cycle, from base yield)
Second tuning => 143 x 1.1 + 10 = 167.41 %
Third tuning => 167.41 x 1.1 + 10 = 194.151 %
Fourth tuning => 94.151 x 1.1 + 10 = 223,5661 %
Fifth tuning => 223,5661 x 1.1 +10 = 255.92271 %
There's a multiplier of 10% for each tuning not only that but the 10% is added for each tuning but not to the base of 121%, but there is more, on each tuning an extra 10% is added. I really don't get it tbh. The tunings don't really add 10% but much more as you keep stacking in a way you are rewarded for bland fits.
So it should be like this:
First tuning => 121+10 = 141 % (mining amount/cycle, from base yield)
Second tuning => 143+10 = 153 %
Third tuning => 167 + 10 = 176. %
Fourth tuning => 176+10 = 186 %
Fifth tuning => 186+10 = 196 %
They are both percentages so this is the way to add them up imo. Remember there is no stacking penalty here but it makes much more sense to say, do I need that extra 10% boost or maybe some tank would come in handy, simple.
Now for simple stacking penalties:
First tuning => 121+(10) = 141 % (mining amount/cycle, from base yield)
Second tuning => 143+(10/2) = 147 %
Third tuning => 147 + (10/4) = 149.5. %
Fourth tuning => 149.5+(10/6) = 151.666 %
Fifth tuning => 151.6+(10/8) = 152.85 %
You still get some boosting but certainly not worth it for losing valuable slots. This will nerf mining so lets give a tuning buff:
First tuning => 121+(30) = 151 % (mining amount/cycle, from base yield)
Second tuning => 151+(30/2) = 166 %
Third tuning => 166 + (30/4) = 173.5 %
Fourth tuning => 173.5+(30/6) = 178.5%
Fifth tuning => 178.5+(30/8) = 182.25 %
As you can see tunings give now 30% huge buff on the first tuning, but the 2nd stacking gives 50% boost the 5th gives 1/8th boost. Things can get more creative now on how to use your slots. There is still a nerf but this is just an example.
