Nice discharge curves. The 10A and 15A I terminated early due to temperature.
The tail on the curves is how much voltage they recovered when the load was removed.
If I had discharged to the rated 2.5V I would have got more capacity.

The cell temperature is 75C when I stop the discharge.

Doing a 15A discharge on a 10A rated cell is not supposed to work, the cell raches 77C after I stop the discharge.

Conclusion

This is a very good cell with high capacity and good current capability, but it gets hot at full load. This is one of the top cells when you need both capacity and current.
