Specification
https://github.com/w3c/compute-pressure/pull/298


Summary

The Compute Pressure API reports the global pressure state for specific 
sources, such as the CPU. Developers have shown interest in understanding their 
own impact on this state essentially, determining how much they are 
contributing to the pressure or if it is mostly due to external factors. The 
new "own contribution estimate" feature provides this detailed insight. By 
analyzing this estimate alongside the global pressure state, users can better 
understand how their current execution context affects the overall pressure. 
This allows them to make informed decisions and take appropriate actions based 
on their contribution.

Motivation

"own contribution estimated" is an extension to the existing Compute Prressure 
API. It provides one extra attribute to the existing interface PressureRecord. 
The new "own contribution estimate" feature provides a more detailed insight of 
compute pressure. By analyzing this estimate alongside the global pressure 
state, users can better understand how their current execution context affects 
the overall pressure. This allows them to make informed decisions and take 
appropriate actions based on their contribution.

Other signals:


WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it 
has potentially high risk for Android WebView-based applications?

None




Debuggability

None



Is this feature fully tested by web-platform-tests?
Yes
There are existing wpt for compute pressure API: 
https://wpt.fyi/results/compute-pressure?label=experimental&label=master&aligned
 This feature is only one extra attribute into an existing interface.
