Wrong survival scores for some pairings
The server doesn't use Robocode. It simply processes battle results sent by clients. Numbers from 0 to 35 in the case of survival scores.
I know the server throws results away sometimes. It records results on one side of the pairing, but not the other. In an attempt to decrease the number of database accesses and cloud service fees.
But it only reduces the amount of battles. Would explain a low number of battles, but not low scores on all battles.
