Point 1 is calibrated and accurate when speed is steady. However when accelerating the point one swings to the left and when decelerating the point one swings to the right. Has anyone seen this?

Typically related to the wires for your outboard being to close to the P1. When you accelerate the voltage in those wires increases, leading to the magnetic field around the wires increasing.
I've had a similar thought, so let's walk through this. Ignition, speedometer, and trim should be the only wires going from the console area to the motor correct? Of those the only wire that should have a change in voltage would be the speedometer. My speedometer is currently broken and not displaying any speed, which makes me believe the wire voltage shouldn't be changing. However, it could be that the gauge is bad. Can I unplug the speedometer and remove voltage from the sending wire?
Voltage in the ignition-wire(s) jumps as voltage in the battery jumps with the increased charging.
On many typical boats used for angling (mine included) the ignition wire runs in the gunnel right under where most of us put the P1 (again, me included). Photo from test-mounting my P1:
In my case I used led-tape under the P1 to shield it from the cables running an inch or two below it. Led-tape is typically used in golf to balance the clubs so you find it in any shop selling golf-equipment.
I left out that once I am done accelerating the heading will swing back to correct. Since that's the case, could it still be the ignition wire? Wouldn't the voltage from the increase in charging be the same once I am at max speed? If so, why would it swing back to correct heading?
Did you put the lead tape on the bottom of the point 1 or on the top inside of the gunnel?
My point 1 is set up similar to yours.
Thanks for all the discussion so far, very helpful.
