So you would suggest that compaction is a non-issue if the recirc is slow enough? I'm certainly in no rush to recirc, as long as my temps remain stable and my mash-out happens evenly across the bed.
Things that affect recirc flow/rate and compaction:
1. Water/grain ratio - 1.75 to 2.50 is recommended
2. Grist Bill - Wheat, and corn/oats/rice are not your friends
3. RiceHulls - More of these alleviate the "gumming" that #2 provide, and allow a faster recirc rate.
