AGC settings for M110A?

[Buck]

My STANAG primer for M110A says that AGC should be set at less than 10 ms in desensitization and less than 25 ms in resensitization. They were not, I assume, thinking of SDR when that was written. I have been using AGC set to Fast, but I wonder if there are settings in custom AGC that would do better. I use RX2 for the data terminal modem, and RX1 for voice. Thanks for any advice.
