The Q would be about 3/4 pts. (Difference is about 5%). If I have an 
implementation that works its math in quarter points (smallest unit that 
I've come across in run-of-the-mill software) then that could be your 
error. Is that something that real implementations do, or do they work 
with much higher internal precision?

It isn’t mentioned in JLREQ, however.
