Seajack, I'm talking the same as you.
Real world scenario - you're stationary waiting to turn, a car flashes you to go you hit the throttle and everything goes into slow motion, the car doesn't move then suddenly it's warp drive! The delay is only momentary but it feels like an age.
Likewise, as you find, you pull out hit the throttle and again there's thinking time before the power kicks in.
Once it's going it's fine, it's just the time taken to get going that's the problem.
Mine is better in Spot/Sport+ than Comfort, but only better - not right!
