Hey Josh, nice work there. Nice to see someone humble enough to know when things don't work as expected and learn from it. [In case that doesn't come across right, it is not a back-handed compliment.
As for the rest/pause sets, I do
like them. You get really solid lifting in a short time. Wouldn't be a bad idea to try them out. I use 7 sets, with 30-30-60-60-90-120 seconds rest between.
