- 8.3% average globally doesn't necessarily represent 8.3% of your users or market.

- 8.3% is almost much larger than the metric you actually care about -- the percentage of users that will not use Chrome (or your desired set of supported browsers).

Of course, I used that figure because it’s what the poster used. I looked up what it is for the product I work on and it’s actually only 4% — still an order of magnitude larger than it would need to be to consider not supporting it.

The desired set of supported browsers will always come down to metrics.
