Hmmm....mind if I recap this to make sure I understand?
Once the AOB's are processing a decent amount of ammonia in 12 hours, I will have a nitrite spike. Once I notice that the spike is coming down...I should do a big water change and cut back the amount of ammonia to 2ppm. According to what he's saying, NOT doing the water change is kinda leaving the NOB's with a sinkful of dishes to wash and no help with putting them away making the chore take longer than it should have to
Your nitrite spike will start now. As soon as the AOBs start processing the ammonia, you will have nitrite. So long as the nitrite level is rising, you can otherwise ignore it until you have the AOBs processing 4ppm in under 12 hrs. When you do, do a big water change to bring nitrite down to a measurable level, and cut back ammonia to 2ppm. This will help the NOBs with their "sinkful of dishes", and hopefully speed up your cycle somewhat.
Then, once nitrite falls back to 0, crank up ammonia to 4ppm again. The AOBs and NOBs will take a day or 2 to catch up. You are then striving for the ultimate goal To add 4ppm ammonia, and test 12 hours later and get results of ammonia 0 and nitrite 0. That means you are cycled.
