User blog comment:Homuhomu123/Trigger Rates & Effectiveness of Anti-Air Cut-In (AACI)/@comment-25784159-20150509163521/@comment-25477086-20150511180754

You can see the data with F12 in chrome as Homuhomu mentioned. Under network, filtered by /api i think it was, you'll get a large combat entry which will appear a second after you select a formation. Inside you'll find a section like this:

"api_stage2":{"api_f_count":46,"api_f_lostcount":0,"api_e_count":43,"api_e_lostcount":34,"api_air_fire":{"api_idx":0,"api_kind":1,"api_use_items":[122,122,106]}},

api_air_fire means AACI happened

api_kind being 1, 2, or 3 for Akizuki is entirely based on the AACI equipment being carried (referenced in api_use_items which refers to the equipment IDs)

Thanks for putting this together Homuhomu as I generally shy away from JP sites as I can't read that stuff.
