PSA: The difference in my pieces after switching to a new annealing schedule

I was having a lot of issues with stress cracks in my thicker sculptural work, maybe one out of every three pieces. About six months ago, I started using a slower ramp down schedule I found online, adding an extra 50 degrees to the hold and doubling the cool down time. The change was huge. I haven't had a single piece crack in the kiln since I made the switch. Has anyone else tweaked their annealing cycle and seen a big improvement?

That's awesome it worked for you, but just a heads up, adding 50 degrees to the hold temp is actually a pretty big jump. Most schedules I've seen only tweak the time, not the temperature itself.

See this everywhere, people skipping steps.
