Ooh, that's great you got a nighttime +6! I'm impressed. I was never much of one for the alarm-clock tests ;-)
Are you planning to go up to 1.8 at night too? Looks like there is room for some tweaking there. I am still m-y-s-t-f-i-e-d why he rises so much faster after the +6 at night, but not in the day. And the consistency of it too is pretty amazing. It's like he has a secret stash of m&ms he takes out at 3 am or something.
