Caliber is a word synonymous with the level of ability one has.

When I say ranking caliber, I refer to your ability to rank. This depends on multiple factors: how much time you have, how good your team is, how much do you spend on MS and trees, etc.

If you are not good at ranking as a sender yourself, we don't send to you. It's a waste of time, basically.
