This cell do not have much capacity for its size and is rated to deliver a lot of current.
The discharge curves looks good, they track and has nearly constant capacity up to 20A. Even at 30A there is no dip in the curve.
Conclusion
This cell has good performance also at higher current. The capacity is not much better than a 18xxx cell, but it maintains higher voltage during discharge.
