Would this be considered good progress?

I started out at a consistent 800-900 ranking in early October.  Over the past two months I've improved to the low 1300s. Is that good progress for 2 months or not?

Plus I think my current rating isn't exactly representative of my current skill. I think I would be around 1400 if I didn't play when I wasn't in a good state of mind (sleep deprived, just woke up, etc)

How would anyone else know how much work you've put in or what your capabilities are? Post some of your non-drowsy games if you want help.

In yer ratings, tha's fine, in yer play, yeh gotta pos' a game.

Or geddit analysed.

Yup.

Although th' computer 'nalysis en Chess.com's been frequently criticised by th' players.

I'd say is a good progress, indeed. Btw, as it happens for different time controls, I have a rating for my sober play and another for my drunk one. Unfortunately the results tend to be the same!
