Despite played match counts and also winning percentage, Why my manager points too low ?
hello mate, please look this post that explains how manager points work,
Every slot you have has an individual ranking. If you play on all 4 slots, you'll have 4 positions on ranking. The position shown on user profile is the slot with the highest ranking. The points taken into account to determine your position on ranking are calculated this way:
Points from last 180 days will count 100%.
Points earned on next 520 (from 180 until 700) days will count less on different levels of percentage until they are ultimately counted at 1%.
All points older than 700 days will count 1% for your total.
Also it would be nice to check common questions topic.
