Q re: adding second series, 2 hours??

[Guest guest]

Hi. I recently read that practice should take 2-3

hours. I've just added half of second series to my

practice and the whole thing takes just an hour and 20

minutes. Is it that after completing primary series one

should then do the sun salutes and standing poses a

second time and then do the second series poses (and the

closing poses just once). Please help. Thank you.
