Like Kat said, INGII is not working properly on simulator, in fact a single CSII will complete the synth under INGII if you get 1300+ during Flawless, though my stats are significantly higher than min. so not sure what the req. is for it.
I like the final 2 step completion under INGII because it not only provides quality boost but it allows me to take a lot of ToT during flawless, I believe you only need 1189 progress during flawless to complete under ING II + 2x CSII. (again my stats are significantly higher than min.)
