Markus, thank you for quickly taking a look at this. It is agreed this issue is not an easy one to deal with, and more an issue of "how accurate is it?" versus "is it 100% accurate or not?". However, this was marked as a bug because both Excel and Gnumeric correctly yield -1. Looks like a great opportunity to improve LO! :)
