I had the pleasure of mining alongside a max boost rorq in a normal mining fleet (barges and ventures). My hulk was filling faster than I could jetcan.
Which begs the question, why does anyone multibox (x) rorqs when the apparent Rorq (max boost) + (x-1) Hulk yield seems be double (if not more)…and a lot cheaper.
Pretty sure I made 10+mil per minute in Hulk rigged for Mercixcot yield + t2 merc crystals under rorq boosts (I mined 640 million isk in the first hour and that was with a 10 minute bio/coffee break).
Around 7 mil per minute on Spod and 5.4 mil on Crimson Ark ( I think Crimson Ark ISK/minute would have been higher had I not taken 20 minutes for lunch).
