Increase your chance of finding a Rare (Eq2 horse)

It seems that right as a new instance of a zone comes up the chances of finding a rare in one of the nodes that has never yet been harvested in this new instance is greatly increased. My guildie has tested this now several times and found it to be true. He explains it saying that the when a new instance comes up all the nodes are brand new and ‘reset’
Anyway, when a instance hits 100 poeple a instance is created. So right around 6:00-8:00 PM everyone is getting home from work, you can bet a new instance will be forming. If you are there as it forms, sprint as fast as you can to your favorite harvesting spot of the zone and greedy grab every node you can find.
For example, a while back a guildie and me were working on the PGT’s skindancer part. He /who’d the zone and found like 98 poeple in it so he said wait for a new instance. As soon as the zone opened I ran straight for the PGT quest starter but my guildie stopped to gather casually the nodes in the riverbed on the way. In just a few minutes, by the time we reached the giants, he gathered no less than TWO steel clusters and a severed fir and linked them all to me.
He told me later he manage to get another rare on the way out.

Anyway, my guildies swears that this is not just luck and that he has found it to be true many times.
I thought that this might be of some use to the members of the forum and went ahead and posted it even thought I cannot confirm this 100%.
