Hello Bill,

If there is that much difference in ripening, I'd say they are not the same 
variety. Size and crop loading can differ from year to year, but I've never 
noticed a great change in ripening dates when moved to another understock 
or area. That doesn't hold true if moved to a radically different USDA zone. 
Varieties removed to Louisiana for example ripen much earlier, but if both 
were moved to the same area I'd expect the Geneva Long to still ripen later 
than the NC-10.  

On that subject, I've grafted Juhl and Yates onto the same understock and 
both fruited and are dropping simultaneously. I've asked more than one 
visitor to look them over, examine the fruit and see if they can see a difference. 
None has been found. This repeats and seems to confirm Claypool's test, but 
I want to give it a few more years. When plant DNA testing becomes more 
reasonably priced I will run them.
