A live, working case study · Day 58, and still running
One car, from the day it was bought to today: the switch from gas, charging with no charger at home, the delivery shifts, what a mile costs and the company built in the hours between. 25 steps in 8 chapters.

Why a software studio put one car, one driver and every mile on a public record.
Case 01Step 1 · The reason
One way to build a business is nights and weekends around a job. The builder chose the other way: delivery blocks on a flexible schedule, then software, events and clients in the hours between, with the car and its numbers on a public record.
The ownerStep 2 · The driver
Four gas vehicles came before this one in about a year, each bought for a job and sold when the job or the math changed.
Three tracksStep 3 · The income
The tracks are ranked, not listed. Software is the lead. Sourcing and the audience come second. Delivery is the bridge.
From gas to electric, with no charger at home.
Start hereStep 4 · New to EVs
The first switch from gas to electric, in the order it happened: the decision, the first week, living electric, the ledger and the battery.
79kWh of 79
measured, one reading
Step 6 · The battery
The pack read 79 kWh at 121 cycles, its rated size. A second dated reading is needed to show change.
Every kilowatt-hour bought at a public charger.
41.3¢a kWh, blended
measured, from the invoices
Step 7 · Charging
$576.93 for 1,397.3 kWh across 44 charges. A typical stop runs 21 minutes, 29% to 80%.
7.12%never reaches the battery
measured across 37 charges
Step 8 · The plug and the pack
7.12% of the energy billed never reaches the battery. Every cost per mile on the site already counts it.

Step 9 · Week of October 11
The week's cheapest charge took no detour: the same Supercharger bills less at some hours than at others.

Where the miles went, and how much of the driving FSD (Supervised) did.

Step 11 · 4,766 miles
599 drives since August 25, with a driver supervising every mile. The share measures use, not time saved.
1,085.8miles that week
measured and modeled, the Record's own split
Step 13 · Week of October 4
The apps pay by the delivery and count each delivery's distance. The car's own record counts every mile, the drive to the first pickup and the gaps between orders included.
What the delivery work asks of the car, and what it pays.
$19.65an hour, on 11 days
hours on shift, app clock and the owner's hours
Step 15 · Hours on shift
A shift runs from the first delivery's start to the last one's end. On October 14 the app's clock said 4h19m and the shift ran 5h00m: the shift counts the waiting between orders, and two orders made together only once.
58days on the Record
Step 16 · 58 days
Every day of the case: the miles, the charging, the money and the hours. $1,752 earned on 21 days. A day with nothing on it is a gap, never a zero.
What a mile costs, and how to price it at another rate.

the gas vehicles modeled at their own mpg
Step 17 · Cost per mile
Electricity only, as charged, against the four gas vehicles it replaced.
A calculatorStep 18 · Any rate
A calculator prices this car's measured 293.2 Wh a mile at any electricity rate and sets it against a gas car's mpg.
The numbersStep 19 · Every figure
The headline figures for any day, week, month or quarter. Each one opens to the page that holds it.
The work done in the hours between the shifts.

Step 20 · October 15 to 18
The car's trips to the job are its own record; the rest is the owner's count. What the show brought in is not on the record yet.

ALL JACK, WillerTime’s waterless car detail spray, cleans and shines in one step on clear-coat paint, wheels, trim and tires, WillerTime says, and all six of its ingredients are printed on the label. PaddockGavin has a paid partnership with WillerTime.

Case 03Step 23 · Another case
An app that names a car and prices it from auction results: what its nightly sweep found, what is in its store and who asked it.
Still running. The latest week, and how to read every figure.
Still runningStep 24 · Week of October 11
The latest complete week: 571.7 miles and $262.54 earned. A story every week asks one question and says what it cannot tell.
The keyStep 25 · How to read it
The mark beside a figure says how it is known. The Legend defines every name, mark and equation; Sources says where each figure comes from.
