Hi GardenerBoy, no problem.
It doesn't matter how many cylinders you do per day, as long as you give yourself time to do each one to the best of your current ability (ie without rushing), and make sure you're sticking to the 50% rule introduced in lesson 0.
For cylinders around an arbitrary minor axis you may be able to get more than 6 on a page, as you're only doing error checking lines for the minor axis of the ellipses. I'd still cap it off at about 10 on a page though, drawing small can make it harder to engage your whole arm, resulting in stiffer or clumsier linework.
Cylinders in boxes need more room on the page as you'll be performing a lot of line extensions to check your work, I was doing between 2 and 5 per page.
