I couldn't find the record option maybe I'm just blind
So I set action to CPU (in training of course)
The instinct meter to infinite
Then back to the game, activate instinct mode with HP+HK (RB+RT by default) or up on the RS then keep pushing RS up constantly (or HP+HK it's quicker and easier to do with RS) and it will pop
You may not get it every time and get a combo breaker, the achievement is not 5 in a row, it's just 5 in one instinct mode. I definitely didn't get 5 in a row
Any questions just ask
