I don't have a lot of time right now so don't expect the fancy graphs. Just a quick test of it mounted to an MCPCB which in turn is mounted to a block of copper.
This is an R5 flux bin.

Keep in mind this test is room temp not the 85C test which would be more real world but considering we all still have in mind the specs of old LEDs tested at room temp I figured it would make the comparison easier.
My recommendation is no more than 2A if you want to push it harder than spec and are using an MCPCB. I will also be testing one mounted direct to copper soon.
And no I did not capture the Vf. Sorry.
