P.s. hard to type on mobile phone... appreciate the sequential vids :)

Hullo, I was under the impression that the 'slump' in the top part / final pour should be less, eg first 75% of hole at say 20, and final 35% at 6. Is this appropriate? Thx

@logieberra, don't know to tell you the truth, however I can say that my concrete pier foundation is very solid even with a heavy mount on top of my steel pier. I never found any rules/recommendations so just went with what looked/sounded reasonable.

Thanks for the encouragement. Time to get back at it I think ... stay tuned for a Thanksgiving update!
