The predictor combines historical pump-price patterns and recent trends with crude and wholesale inputs. Those signals do not establish a known future pump price or a fixed pass-through delay.
How the prediction is built
The heuristic combines a day-of-week comparison, a recent daily-price trend, changes in WTI crude and changes in Edmonton wholesale rack observations. Its conversions and thresholds are model assumptions, not verified market laws.
A weekday pattern can reflect a changing station sample or a wider market trend. Missing weekday observations can also trigger a preset fallback in the model. We have not published a station-matched weekday study or a backtest that establishes a reliable cheapest day.
Recent station coverage and dated market observations must pass readiness checks before a verdict is offered. An input shown below is context; its presence alone does not establish that the whole forecast is available.
For a practical comparison, multiply the possible change by the litres you would postpone and subtract any extra trip cost. The savings calculator and timing guide show worked examples. The coverage page explains the underlying report limits.
FAQ
Is Tuesday always the cheapest day to fill up?
No fixed cheapest weekday is established by the evidence published here. The model uses historical patterns as an input, not a guarantee. Compare current reports, your fuel needs and the cost of an extra stop.
What does forecast unavailable mean?
The required station or market observations did not pass the model’s readiness checks. Unavailable does not predict stable prices. Read the reason shown with the result and use current station reports to plan a practical fill.
Is confidence a probability of being right?
No. It is a model signal-agreement score, not a calibrated probability or a measured pump-price accuracy rate. We have not published an out-of-sample accuracy evaluation here.
What is a rack price?
A wholesale terminal price, which is different from a retail pump observation. The model treats its movement as one input. It does not establish a fixed retail pass-through or an exact price change at your station.
Can I get alerts?
The alerts page offers confirmed-email threshold and forecast subscriptions. A threshold alert reports a qualifying observation; it does not reserve a pump price or guarantee a saving at a station you can reach.
