Audited planning profile
This lean half-year profile applies a 0.75× editable baseline across 6 model periods to the ev ownership buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Review the assumptions midway because prices and usage may already have changed.
Live fuel prices, charging tariffs, insurance quotes, taxes, incentives, depreciation and repair events are not fetched.
Use current local quotes, measured consumption and the vehicle's service schedule.
