Pat,
This is consistent with my limited observations. I germinate maybe a dozen seeds of each cross and refrigerate the rest. If I'm sharing some a year or more later, I'll float a few just to make sure they are still viable before mailing them to someone. Seeds from my very first hardy Hipp. cross involving H. reginae are still viable after at least six years in the fridge. I wouldn't generalize that to all Hipps, but certainly some Hipp seeds are tougher than many folks might think.
Your results are especially valuable because of the great interest in breeding with H. papilio. Those are the kind of seeds people would love to share!

I have conducted an experiment. In April 2022 I gathered 30 fresh
*Hippeastrum* seeds, with obvious embryos, from a cross I made on *H.
papilio*. Using the "Float" method I germinated 10. No problem with all
10 germinating. The remaining 20 I placed in a Ziplock bag and put into my
refrigerator, which holds steady at about 35F. This year, April 2023, I
floated half (10) in a plastic glass and *all 10* *germinated*. I returned
the Ziplock to the refrigerator with the remaining 10 seeds. I expect to
float the remaining 10 next spring.
