physical% complete vs schedule % complete?? (Rodel pls)

Dear Rodel,

Please advise me about this subject:

Am I right if I compare performance % complete (physical % complete) vs schedule % complete???

Note:
- My schedule is cost loaded (calculate cost from units)
- I am measuring progress using physical % complete
- Schedule % complete come from my baseline schedule which is not progressed.

Thank you in afvance
