My 2018 LR RWD EPA estimate is 234 Wh/mile. You do not say whether yours is a RWD or Dual Motor. I am not sure what your 2021 estimate is but I would expect somewhere around 240 Wh/mile.
Looking at your kWH/mile and converting to Wh/mile, you have trip at 230 Wh/mile. Your expected miles is 244, your driven miles is 145 and remaining miles is 120. So 145 + 120 is 265. So your range miles is greater than expected miles.
Another trip is at 310 Wh/mile. Your expected miles is 288, driven miles is 134, and remaining miles is 88. So 134 + 88 = 222. So in this case your range miles is less than expected.
Your driving speed, weather, wind, elevation change, etc. all affect your Wh/mile and your range miles. Look at your Energy Graph Consumption chart. The dotted line is your EPA rated Wh/mile. If your current consumption is above this line, you will get less range miles. If it is below this line, you get more range miles.
