I tried Belma too. It is high enough in AA (10.4%) to be a bittering hop, but I was intrigued by the flavors ("very orange, slight grapefruit, tropical pineapple, strawberry, and melon aroma."). Unfortunately at only .08 for total oils you'd have to use a lot of it. So it is now in the category of 'meh'.
I think you mean 0.8, right? Which is still pretty low for a modern IPA hop. And total oils isn't the final word. For example, Centennial has more total oil than Mosaic, but Mosaic is a much more dominant hop (at least to my palate). If Belma is truly 0.8 mL/100g oil, then that's the same as Motueka, which has a lot more flavor/aroma impact in my experience.
Total oil is a good starting point, but there is certainly a lot more going on that we just don't see good data for (or even understand yet).
Maybe I'll have to just use up all of my Belma in a small batch to see what happens if you really push the limits.
