Hi all,
Is there any client or code that currently implements BIP 100? And how will
it be deployed? WIll the initial fork be deployed in the same manner that
the max block size changes are deployed described in the bip?
Thanks

Great questions.
- Currently working on technical BIP draft and implementation, hopefully
for ScalingBitcoin.org. Only the PDF is publicly available as of today.
- Yes, the initial deployment is in the same manner as size votes.

I have been reading the pdf and one thing I can't figure out is what you
mean by "most common floor". Is that the smallest block size that has a
vote or the block size with the most votes or something else?

20th percentile, though there is some argument to take the 'mode' of
several tranches

Mode could be ruled out immediately. Just consider this: 34% 8MB, 33%
1.5MB, 33% 1.2MB
I personally believe the median is the most natural and logical choice.
51% of miners can always force the 49% to follow the simple majority
choice through a 51% attack. Using median will eliminate the incentive
to 51% attack due to this reason. The incentive to 51% attack will exist
when you use any value other than 50-percentile. The further it is from
50, the bigger the incentive.
Having said that, I don't think it is an absolutely bad idea to use a
value other than 50-percentile. The exact value is debatable.
However, if you use something other than median, you should make it
symmetrical. For example, the block size will increase if the
20-percentile is bigger than the current limit, and the block size will
decrease if the 80-percentile is smaller than the current limit.
