Travis,
You definitely are confused. Any hours flown post private or solo can be logged as PIC. SFAR 73 states that you must have a minimum of 200 hrs total time and 50 hrs in an R22 to be able to instruct in the R22. You will also need to have a PIC endorsement from an authorized instructor every 12 calender months to be able to fly solo in the R22, unless you meet the 200hr total/50hr R22 requirement.
