What are the recommended frequency settings for SMA SB power control

I have a SMA SB Tl21 series solar inverter which has a default setting of 51 Hz for Start of Frequency power control and 52 Hz for end frequency for power control. What settings are recommended then on the Multiplus for "Start reducing Power Frequency", "Output Power reduced to minimum Frequency", and "Converter will disconnect when higher than Frequency" ?

I would go with something like this:

You might need to tweak "Output Power reduced to minimum Frequency" , but 51.8 should get you in the ballpark.

Does the Multiplus have fine frequency control or does it use brute force freqency shifts to control PV power production
