cudt for Kain-Fritsch

[ehsantaghizadeh]

As I found in WRF User's Guide, for cudt is written "minutes between cumulus physics calls; set to 0 (call every time step) when using all cu_physics options except Kain-Fritsch". There are Kain-Fritsch (KF) cu_physics=1, Kain-Fritsch (KF) cu_physics=10, and Multi-scale Kain-Fritsch cu_physics=11. Is the sentence above right for all of these three options? So, what should be choosen for cudt for these three options, or each of them?
I hope my message is clear, and I look forward to hearing from you.

CUDT can be applied to Kain-Fritsch (KF) , Kain-Fritsch (KF) , and Multi-scale Kain-Fritsch .

When you run WRF with any cumulus scheme of the above three, you can set CUDT to control the time to call cumulus.

Could you please explain more about the mentioned phrase above: "minutes between cumulus physics calls; set to 0 (call every time step) when using all cu_physics options except Kain-Fritsch", (Namelist Variables — WRF Users Guide documentation)
