For those claiming 100% is not real, I managed to get my Lola (~70 +100) and Val Red Battler (89+100) that way, however that was a while ago so that is of no real help as the system could have been changed in that time.

I have also started recording the results of my battles since the last event began in the hopes of figuring out drop rates and chances of getting shards/100% and tabulating the results.

Trinket took 260 battles ending at 101/100 for the long grind. I, sadly, did not record shard amounts so I can't say shard average but will be recording that from now on as well. Will post more results after the next couple of events when I have more data collected.
