I found this explication //// BestShare: If your miner or pool computes a hash value that is lower than that maximum, then you or the pool have solved a block.

in this link : https://support.bitmain.com/hc/en-us/articles/360013577314-Miner-status-page-explained

is that mean  :  if my share is less than my best share so i solved a block ?
