EV Miles equivalent for cost of a Gallon of Gas e$mpg

Hi all. Never been much of a lover of eMPG as it does not take into account relative costs of the fuels. So I came up with a way to compare my EV mpg with my ICE mpg.
To get a direct comparison, I asked how many miles can I drive my Bolt for the same cost as a gallon of gas.
Calculation goes like this.
Current gas price here in Texas is $2.499 per Gallon.
current off peak cost of 1 KW of electricity is 6.93 Cents.
my juicebox L2 Charging Efficiency is averaging 93%.
my current lifetime Miles per KW is 4.32.
Therefore, EV equivalent Mpg = 2.499/0.0693*93%*4.32
Which equals 144.9 e$mpg.
My current lifetime e$mpg is 110.3 e$mpg over 5700Miles.
Wondering how many miles others get per the cost of a gallon of gas?

I'm also in Texas, but I use Breeze wind power at 8.1¢/kWh. I get 4.5 mi/kWh ... your math works out to 128.6 using $2.499 per gal.

I usually tell my co-workers I spend 25¢ to get to the office where they spend $$$ ... they get it. Then we go for a drive to experience smoothness, quietness, instantaneous response, regenerative braking, and then they REALLY get it: a better driving experience for less!

My wife and I occasionally carpool together. The round trip is 100 miles on interstate in NJ.
If we take her Subaru Crosstrek, fuel cost $8.33 ($2.75/gal, 33 mpg).
If we take my Bolt, the cost is apx. $3.75 (4m/Kw x .15/Kw).
NB, my efficiency varies from <2.5 m/Kw in winter to >5 m/Kw in summer.
However, I have not counted frequent deeply discounted or free charging.

First week of ownership and I've been getting free L2 charging, so it's like 999 e$mpg for me. :)

Working out the numbers from this particular post...

$4.73/gal
$0.042/kWh or $0.145/kWh
4.00mi/kWh (inc. loss)

4.73 / 0.042 * 4.00 = 450 e-mpg for the apartment charger
4.73 / 0.145 * 4.00 = 130 e-mpg for the public DCFC
