In an ideal world, I agree with time on + PCT = time off
Not sure how many people subscribe to that though... at the very least, consider that sustanon has an active life of up to 3 weeks ...So you'd have to wait at least 3 weeks + PCT (what does your PCT look like?) Then wait however long it takes for your PCT anciliaries to clear and have some bloodwork done. For example, clomid has a half-life of 5-7 days, so you should wait about 2 weeks before getting bloodwork. Then you'll know for sure if you're good to go with the next cycle.
