Yes. the fractional difficulty is currently very high (.96 or more) This means only 4% or less of the chains suggested by the chainsperday value would be accepted by the network.

If my understanding is correct, when we hit 10.000 diff, then the chainsperday value will change to a much lower number since its related directly to the whole integer value of the difficulty.

If you only have one (or a small few) machines then you probably wont see a block each day anymore.
