The numbers I've monitored on the app were 239 to 240 volts under load and 40 to 41 MPH charging on the MYP. I was hoping to get the constant 44 shown on the chart. The electrician said that this use to be the case, but the software (or design) of the MYP '22-'23 changed somewhere, and now they get only 40. Was wondering if there was a work around.
No, there is no work around, because energy is not put in the car in miles, its put in in kWh. You are not missing anything at all with your charging rate. if you are charging at 48 amps at 240 volts, you are getting 11.5kWh of power, same as a model Y Long range.
The reason I posted the chart was to show you that "miles" really does not matter as a metric for filling your battery. A model X charging off the same connection would show an average of 35 ish "miles" shown, but both would be receiving the same amount of power from the wall connector.
A model Y performance has less range than a model Y long range, thus it uses more energy per mile, thus the car shows fewer miles filled up for a given amount of provided energy (this is what
@LoudMusic ) said earlier.
Mine shows 43-44 because my voltage runs hot, so I am actually putting in slightly more power at 48 amps than you are:
Convert amps to watts with our electrical conversion calculator, plus learn the formulas for DC, and single-phase or three-phase AC circuits.

Your stated charge is 48 amps times 239 volts (11,472 watts or 11.472kW) or 48 amps times 240 volts (11.520 kW).
Mine is 48 amps times 244 volts (11.712 kW).
240 volts is normal for home use, my home runs a little hot (I am close to my transformer, and also have powerwalls).
TL; DR = Nothing to fix, nothing is wrong, and looking at miles as a measure while trying to talk about power filling a battery can mislead you. Look at power, not miles.
