10 should be fine - the request supports pagination and there is a limit on payload sizes on some relays.

Yes, I learned that the hard way, about the 64k default limit on strfry relays! The thing is that Damus doesn't seem to do any pagination requests....

Or possibly just default to 50 results, instead of 10? Although there might be a reason you chose 10....
