The following analysis is based on the 100% mod drop rate during the weekend of the double drops: 5/27 and 5/29
Based on the data gathered by several users (Thanks to everyone that submitted), the data set had 1100+ input points, by color, by position and by primary stat. The information also included the amount of Speed or Offense secondaries.
Just about 35% of the mods that you'll get will have secondaries. Now it is time to see how many of these will have speed or offense.
With grey mods:
Speed: 5.57%
offense: 4.76%
Without grey mods
Speed: 15.94%
Offense: 13.62%
What this basically means is that out of the 100 mods you farm, you'll only get about 5.7% mods that will have a Speed secondary stat (without taking into consideration the color of the mod.
Percentages to get a *color* mod with speed secondaries (based on gathered data):
Green: 1.71%
Blue: 1.71%
Purple: 1.17%
Gold: 0.99%
After farming more than 350 mods myself, I noticed the large amount of left side mods (Square, Diamond and Circle) in comparison to the drop rates from the other side.
The above information is actually interesting. This means that by every 2.61 mods you get from the left side, you'll get 1 mod from the right side with a 72.3% chance of getting a left side mod and a 27.7% of getting a right side mod.
What worries me about this is that the left side mods will always have the same primary stat, offense - defense - health/protection in each position respectively. Now imagine what you have to do to get a Speed arrow, even worse, a critical damage triangle. Let me tell you the odds with the following table
Oh! At least the drop rate isn't that bad regarding the MK Tier, 80% will be a MK V mod, so you'd have to be very unlucky not getting that Crit Damage triangle with speed secondary.
So basically, what I want to show here is the probability to get a Critical Damage Triangle being 0.91%. This means that only 1 out of every 100 mods you get will have this stat. Now, if you want it with a speed secondary, you'll have to be more lucky because the chance of getting this is a solid 0.05%, but hey, let's keep stacking our inventory with those juicy Defense Diamonds with a solid 24.63% drop rate.
But, wait a second, how many of those will be MK V mods, because an MK III is not as good. Well, here is the tier distribution:
Disclaimer: As always, remember that there is probability involved, so RNG makes a big part of our mods. If you have tons of crit damage triangles with speed secondaries, well, you are really lucky lol.
