Overview
Deg Prediction covers three widgets, one for soft, medium and hard. Each shows the degradation rate the Race Strategy Tool was handed for that compound before the race started, with the tyre life it applies over. This is an input, not a measurement. It is the number the strategy engine is planning with, so it never moves as the race unfolds and it does not follow the playhead. Put it beside Live Deg Prediction to see at a glance whether the race is degrading the way the plan assumed.These three are the only widgets in the set that read a parameter row rather than a metric or a raw channel. If the pre-race bundle for this weekend was never loaded, they say so rather than showing a stand-in figure.
What It Shows
The life is shown because a degradation rate means little without the distance it applies over. If the bundle carries a rate but no life for that compound, the brackets are simply left off; the rate on its own is still true.
Data Behind It
The figures come from the storedrace_data parameter row for this weekend, the same bundle the Race Strategy Tool is fed. store/selectors.ts’s compoundDegFromParameters resolves it:
- It looks for the parameter set for this exact (year, round), preferring the active row rather than relying on the gateway’s ordering.
- Within that row’s
race_data, it reads the per-compoundprimarydegandprimarylifefields off the driver block. These are per-weekend inputs, so every driver carries the same pair. - A row that carries no usable compound at all reads as absent, rather than rendering three empty widgets.
model_id or model_version, and nothing appears for them in the picker’s version list.

FAQ
Why does this number never move during the race?
Why does this number never move during the race?
Because it is not a measurement. It is what the strategy engine was told before the race, so it is fixed for the whole session. The live measurement is the Live Deg Prediction family.
It disagrees with Live Deg Prediction. Which is right?
It disagrees with Live Deg Prediction. Which is right?
Both. One is the plan’s assumption, the other is what the tyres are actually doing. A gap between them is the interesting part: it is the strategy engine planning against a degradation rate the race is not delivering.
Why does it say no data when the race is running?
Why does it say no data when the race is running?
The pre-race bundle for this weekend has not been loaded into the parameters store. The widget refuses to substitute another round’s figures.
