Turkish: where is the end of the round

Ok so i am trying out my first pair of toe up socks and i understand the Turkish cast on…I have wrapped my yarn 5 times to get a total of 10 stitches. Now where does the round end? Is it after the first 5 stitches on my needle or is it after i have flipped the stitches and knit the 5 stitches that were first on my cable needle? the following is the link to the tutorial that I was using to learn how to do the Turkish cast on:
thanks in advance for your help!

When you have the 10 sts cast on and ready to do the first round, that’s the beginning/end of it. Mark it with a piece of yarn or safety pin until you get a couple rounds done then you can put a regular marker on it.

ok so the directions say…CO 10 stitches, Setup Round: knit, round 1: KFB the first and last stitch on each needle, Row 2: knit… Repeat rows 1 & 2 until there are 26 stitches on each needle
Does this mean I am increasing 4 times total? Because if there are already 5 stitches on the needle to begin with thats an increase of 21 stitches on each needle…the math doesn’t add up. Maybe I am overthinking this but here is a link to the pattern: http://www.ravelry.com/patterns/library/uzumaki-socks#
thanks in advance AGAIN

Yeah, it doesn’t make sense, especially since the pattern says it’s written for 2 circs or ML which uses one needle. I would contact the designer at the email on the bottom of the pattern and ask for clarification or correction.

I sent an e-mail to the designer and I also researched other sock patterns, from what I can tell (i have never knit socks before so I may be WRONG) I think I am supposed to have 25 stitched total. Alas I have moved on to a more simpler pattern for my first pair of socks from Wendy Knits in which she writes out in excrutiating details exactly what to do! Thank you for responding!

For your first socks you definitely want detailed instructions. Good luck with 'em. Maybe you can come back to this one later, and the Turkish CO is a good one to use.
