No. First off, the Plaid dies not have a 100 kwh battery. It somewhat less than 100, roughly 96 kwh. Secondly, not all of that is accessible to the vehicle. Average utilization of 350 is pretty high, something well below 300 is more typical. I am typically below 250. If I drive at 80 mph continuously, I am just over 300 (unless it is very windy). You should expect to go at least 250 miles if not more. You may need an alignment. Good wheel alignment is critical for maximum efficiency.
Last thing is, quite a bit of energy is consumed by things other than driving, like the A/C, lights, sound.
Since your energy consumption is high, 200 is not really that far off.
