i think there are too many variables to draw a reliable conclusion

That's the reason why GliderReview aggregates a few for each glider, including "fuzzy" ones like comments and editors' review.

i am also starting to think that you'd be
surprised how far a specific glider can be pushed

Well, that would be related to *maximum* distance, not to *average* distance.

Thanks ND for your feedback.
