The cycle time depends on a few things and it's hard to honesty judge. If you have cured live rock that came from an established tank it will go much faster than if you have dry base rock. I believe there was a typo above, you want to wait till nitrites decrease and nitrates increase that's when your cycle is complete. From your test above I would say your close but again that depends on a few things. Are you using rodi
water or tap water? Tap water often contains ammonia and or nitrates so you may be getting a false reading in the fact that the nitrates were already there. good luck.
