[FEATURE] Override variable support for throttle protection ranges (#1315)
Adds support for setting throttle_protection range values using static override variables. sleep_per_download_s has additional support for entry variables since it's used per entry.
We can now experiment with scaling this value based on entry attributes, such as duration. Example:
throttle_protection:
sleep_per_download_s:
min: >-
{
%mul(5.5, %pow( duration, 0.4 ))
}
max: >-
{
%mul(6.5, %pow( duration, 0.6 ))
}
