Loose fill fiberglass has an R-value of 2.2 to 2.7 per inch.

That seems on the low side.

I checked a number of sources and they vary but I didn't see others that low.

I use R-19 = 6" as that is what you generally how you see 6" fiberglass batts listed.

Yes, batts typically have a little higher R-value.
