Projectile Movement homing property not really homing?

I have a homing missile blueprint that I’m using projectile movement to control its trajectory and to use the homing property on it. How do I make finer adjustments to the homing-ness of the trajectory? It travels at an extremely wide arc and I want to tighten that for faster moving projectiles.

Also homing acceleration doesn’t appear to be working. I have an initial speed set to 1000 and acceleration rate set to 100. I assume it would do 1000 += 100 every acceleration update but its not. It will either stay at the minimum set velocity or set its current velocity to whatever the acceleration rate is ignoring the maximum velocity limit that the tooltip claims it wouldn’t do.

Try setting the Homing acceleration Magnitude like this:

Not quite the same problem, but I thought set the Initial speed to 0 and Max speed to another value ,it would be accelerating automatically, but only the velocity works when without homing target, if I set the velocity to 0, it won’t move

can the acceleration work without setting the Homing Target?
