Grand arena match ups problems

Yes I have read that document.  It doesn't excuse a circumstance where one player has four GL's and I have one and another player in the bracket has none.  Unless another player in that bracket has four GL's, there is no chance of victory.  So the skill rating might be where it is do to indifference or glitch.  from the storefront, I can't see that.  But I can see someone with 1.8MM GP more than me and a 4x multiple of GLs.  "read this generic explanation" is an unsatisfactory response.  If I was the person who had 4MM GP less I would be equally livid.  There is no circumstance where that matchup makes sense whatever the criteria.  I have about 5.7 GP.  Do the math.  This circumstance is ludicrous.
