The things that make a difference for return journey would be weather (wind direction or significant rain) or journeys in hilly areas where you are doing a lot of uphill one way and downhill the other way. Your overall average Wh/mile is certainly high so maybe that includes quite a bit of early days sporty driving!
TeslaFi does tick a lot of boxes for $50 a year and gives you an insight to your driving and the car's performance.
If you have a spare Raspberry Pi knocking around you can load TeslaMate to do the same for the price of a donation to the developer.

I've now driven 14,767 miles in my MP3 since 30/09/19. My lifetime is 320 Wh/Mi but approx 2/3 of my total mileage was completed over the colder first 6 months from Oct'19 to March'20. Since March '20 lockdown, I've driven approx 5,000 miles, mostly last summer/autumn and this spring.
Last Saturday, I completed a round trip of 420 miles, using 113 kw/h and averaging 270 Wh/Mi. This was predominately relaxed motorway driving at 70 mph, same day, 12-14'c with a some light rain on the return. The OPs Wh/Mi lifetime average is indeed very high - though some of that will be reflective of the time of year those miles were driven (from Sept'20), short journeys do hurt consumption and perhaps some enthusiastic driving, as others have commented.

A few weeks back I did a road trip that took in Nevis, Scafell & Snowdon from West London and averaged 271Wh/mi over the 1,316 miles. Due to the length of the trip I also went speed limit plus 10% whenever possible. Mainly National speed limit roads.
As per other comments use % for current battery and the very reliable consumption graph for estimating arrival battery %.

I have a ~200mile (each way) motorway trip that I do quite often in my M3P. My usual rule of thumb for range in miles is simply this: battery % x 2.
As a typical full charge will give me 220 miles, so that means an average buffer of around 20 miles range from a full charge, assuming no long stops where the battery will cool down.
Lifetime is 389, because most driving since getting the car has been short local trips.

I agree, that’s ridiculously high. My Model X is 306 wh/mi lifetime (which includes towing). My Model 3 was like 240-250 lifetime. 230 in the summer.

woops that should read 240 watt per mileHmmm...not good : less than 1/3rd mile on a full charge
Thank you Everyone for kind contribution! I have learnt that:
1) yes my consumption was higher than usual but not shocking to most of you (so it is a relief for me!);
2) many factors I have not considered especially the speed (on my way back after the second charge I felt a bit more "adventurous" and at some point I did get a warning message to keep speed under 85 if I still wish to reach my destination w/o re-charge); I really did not think that the 70 to 80 mph difference is so noticeable for battery consumption (as you know it is certainly not noticeable when motorway driving);
3) thank you GriLLA for TeslaFi and manual calculation example!

The 80/90 is massively less efficient than 70mph. There’s your answer! At least you know it’s not the car playing up.
There's a square relationship between speed and energy so @70mph = 4900units @90mph = 8100units or 65% more.

There’s a square relationship between speed and air resistance, but that’s only one part of the energy usage picture. There’s no doubt that energy usage goes up significantly with speed but in reality I don’t think the mileage impact is even inversely proportional never mind squared.There's a square relationship between speed and energy so @70mph = 4900units @90mph = 8100units or 65% more.

Did everyone reference the claimed range of ICE cars before and complain when they didn't live up to the hype?
I don't think they did.
