I sort of cringe a bit when I hear "when inflation control kicks in" or phrases like that (nothing personal against you mtwelve, everyone has been saying it). Ask yourself, have you been sizing your outputs/blocks differently than you would if there was no 1,000 HYP max stake reward?  If the answer is yes, then this is proof that inflation control has already kicked in.

Now the question of "max gen" kicking in.  Well this is a bit misleading as well, because there is a large chance that we don't see every single stake in one day hit the limit.  I think it was biomech that pointed this out, that it is much more likely that we get close to the max coin supply expansion per day, but that it will vary from day to day near that range.

What exactly is "Max Gen" are you referring to the max of 1k per block that is staking per every 30 days? or is it something else entirely?

The max generation by definition is when each stake will be 1,000 HYP, thus hitting the ceiling each time. Right now we are about halfway to max generation. I don't think we will hit max generation for a long time, because people will always be trying to size their blocks small enough to get rewards that are less than 1,000. I think what really is going to happen is that there will be a fight to stay under max generation, this will mean smaller blocks, and smaller blocks will mean higher difficulty.
