Olymp Trade — Wanna sort things out

I have been trading with the olymp trade for a couple of months and should confirm that my journey is pleasant, y'all know, the experience is satisfying.
But it's only if I speak generally, without diving into details. However, there is one detail that haunts me, so to speak. These are payouts on the fixed time trading mode. I mean, potential profit. In fact, I get along with the offered ratio, but once noticed a review from a trader whose payout percentage was over 90% and I was like "lol, what". I don't have such one, mine one is way lower regardless of the asset, so that is the reason why I decided to write here.
So, guys, maybe someone knows what is happening, am I the only "lucky boy" deprived of the increased profitability rate on the fixed time trading mode? If yes, then WHY ME? :D
