Studies on the Bitcoin network have shown that 10% of the times, it can take up to 45 seconds for a block to be propagated to the network - therefore, for a "fast" coin like NobleCoin, with a 60 seconds average block time, orphans are to be expected more often.
I got plenty of NOBL, just havent noticed it for this coin yet =)
SO in POS terms, the more coins you have = the more connections and therefore the better the chance of winning a coin. And since we all use the same wallet for mining POS, everyone is on eqaul footing when it comes to propogating the new block to the network?
