Is not always same.
Based on the recent activity, I also expect more money during my rank up from Platinum 1 to Platinum 2. Because I get a huge money during my Platinum one from Recent Game, Rank Up Reward & Claim. However, my platinum 2 has the same reward.
Since, recent game and waggering activity could be different.
It is basically the reward based on plenty of things that stake doesn't really say. They have a way of calculating it, and it is not a public information, we do not know exactly what matters. Your level matters, your recent betting matters, your wins and losses probably matters, I mean we could probably see the type of game you play could matter as well. No idea what matters the most but there must be some mix of all of these that come into play when they are calculating.
So, someone with a higher level could earn less than someone with a lower membership because of recent bets for example, that is still a possibility and that is why it is always unknown to us what we will get.
