You’re ripping like 0.60”+/6hr at times. Even with clearing there’s going to be compaction on the bottom of those cores as the weight increases on the lower crystals. A little wind will break the crystals down a bit too. So I just find it hard to see 12-15” of fluff in 6hrs during the meat of it.
If you were clearing hourly then yeah…you’re probably getting 20-25:1 hourlies at times.
