If anything, a slower acceleration from the top will help you feel lag pressure, not a faster one.

Start with 'relaxed' hands, swinging smooooooothly, back and forth with just enough grip pressure to hold the club. You'll start to notice a 'heavy' feeling - imagine the club is very, very heavy as you do this. Back and forth, feeling you are 'in slow motion' and that the club is going back and through at the same pace.

You will get to a point where you can really feel the 'load' onto PP3. Once you feel it, stay at that tempo, pure 'swinging' of the club, back and through - HEAVY and smooth. Do this for a while.

Now, you've got the feel of 'loading', you can 'build' speed - which is likely much, much smooooother acceleration and a much 'heavier' feel than you are used to. It may feel that you will hit the ball shorter this way, but once you really get this, trust me it will go as far or farther with MUCH more control. You will know the feel of 'leverage' at impact. Mass supporting impact.

I warm up swinging two or three clubs to really engrain this heavy, smooth, swinging motion. It may seem that you are pausing at the top, but in reality you are just 'waiting' for the club, as your lower body starts the downswing from the ground up.

This is a very important concept and feel to develop. It is the essence of a 'swingers' motion. A hitter may 'feel' this differently, but the club should be 'swinging' just the same.
