Additional things to try:
a)
Programming an external FLAGIN to trip the CS1 fast OCP comparator.
b)
Enabling/Disabling Volt-Second Balance and its associated gain.
c)
Measuring peak output power at maximum input voltage and by decreasing/increasing the debounce value.
d)
Use a higher CS1 timeout condition with an increased leading edge blanking time.
e)
Choosing a different value of R10 (on schematic) to get a different range of protection.
