Hmm... I expected to see some much longer print times being reported. 8-10 hours doesn't seem very unreasonable. I just started, but my longest print was 18 hours. Not super large either, just a monster pencil holder. I don't remember if it was at 0.2 or 0.1mm, but it came out super clean. 25% infill, which is probably why it took so long, no supports needed, no clean-up was needed either.
