For P/Honda-Mrkos-Pajdusakova magnitude,

What you can do is open the "soft02cm.txt" found guide folder and modify the h and g mag to 13.5 and 10 or what ever you wish.

These are the last 2 entries before the MPC name.

Guide calculates the magnitude from these entries.

Probably because, mathematically, it should be that bright. But comet brightness doesn't always follow mathematics.
