I don't know about your bike, but in the advanced setting on my Himiway I can make the throttle work from zero speed without having to pedal at all. It can be set like yours that requires about ¼ turn of crank before the throttle with work.
Personally I really like the throttle working from zero in tight spaces, PAS always kicks in too much for tight spaces in my opinion even when set to PAS level 1 20% motor power. This is only one of the reason I like the Himiway bikes over other ebikes in that price range.
