If more than 1 person sharing a same position with exact numbers, which is highly unlikely due to superbru system (Win, margin, TDM) so they should share the prize money which is allotted to that particular position. It's seems fair practice in regard to other winners also but please let me know what you guys think?
I don't think it's fair. Let's take the current scenario as an example.

As per my proposal only 4 of them should be declared winners. Timon takes 50%. Royse, kpk & Sword splits the remaining 50% ie.16.67%.
But what you say is that there are 6 winners, Timon takes 50%. Royse, kpk & sword take 10% each for coming 2nd. Raptar & Teo also take 10% for coming 3rd. If anyone of the 3 (Royse,kpk,sword) somehow moved to 3rd spot and push those at the 3rd spot to fourth. Then he would get 20% for 3rd position and the other 2 get 15% each sharing the 30% for the 2nd position. Do they seem fair to you?
In this example raptor and teosanru standing at 5th position, not 3rd (If superbru ranking not counting them as 3rd then who are we to make any decisions on their ranking?) so in this scenario this seems okay "
Royse, kpk & Sword splits the remaining 50% ie.16.67%."
Having said that overall i would say that this sample size is too small imo and on micro level TDM seals the final deal, which is missing atm. I know it's just an example but still..
We're talking about more than 1 participants to get exact WB, MP and TDM after 70+ matches, not saying its not possible but odds are way too low.
It doesn't mean that i don't agree with you. You have a valid point, let's keep this discussing going and let others to jump in. I'm sure we'll reach to consensus soon.
