Which chilling requirement to believe for Flavor Supreme Pluot?

Sorry for bombarding the forum with Pluot questions, but I was just made aware of highly conflicting chill requirements for Flavor Supreme from the same source, DaveWilson. Attached are images of the description on their website, and a plant tag at a local nursery I visited today. The website states 700-800 chill hours, the plant tag says 400-500. I would love to believe the plant tag, since it would mean that I have nothing to worry about in term of sufficient chill hours where I live. And from reading other posts about Flavor Supreme, it sounds like the fact that it had no blossoms this year is perfectly normal for this variety the year after planting a bare-root tree.

Should I trust the 400-500 estimate? Do any of you have experience with the chilling requirements of older Flavor Supreme pluot trees you could share?

Based on the fact that the plant tag assumes the patent is still valid, it was likely designed before 2007 (that’s when the patent has expired). So, I would assume the info on the website is more updated. Anyway, chill hours are far from being exact science, it’s a very crude estimate at best.
