I think the opener i posted along the stats i posted is enough to have an idea.
If not:

- Relic i260
- Chest and Legs i260
- Everything else except one ring that is i230, is i250 Alex Gear
- Materias used are IV
Anyway i've recorded the dummy attempt but Youtube said "The video has failed to process. Please make sure you are uploading a supported file type.", was MKV Format and that is supported by Youtube. ._.
EDIT: I just read that Crit Stats not only increases crit chance but also scales crit damage, i also took a look at this video: https://www.youtube.com/watch?v=V2Jy5TX3KAg
And counted 54 Crits, i counted 42 Crits on my attempt, a good mount of my crits came from Auto Attacks instead of skills, i also notice the video user has more HP so i assume Higher ilvl, unless using Vit materia.
And in this video of the mention i made about the dude with 1275 crit (the only video that shows character stats), i counted 65 Crits: https://www.youtube.com/watch?v=tbv5IjAu9RA
