So you may potentially be setting yourself up for a dead pool if a long dry spell hits.
What am I missing?
That is true for the current proportional method, as well as for solo mining. And if it was not, then the pool operator would take the risk on himself, with such low fees, and then you would definitely be left without a pool..
I don't understand if that method deals with pool hopping at all
if not, Multipool will be happy with this
The whole point of this discussion was that the old method is susceptible to pool-hopping, so yes, all the methods suggested above deal with it.
