Filter restriction
How clogged the filter is, vs. a fresh-clean baseline
Hydraulic restriction proxy — percentage above the current clean-filter baseline.
Derived from the W/GPH efficiency ratio (watts per gallon-per-hour). Higher = more
resistance = dirtier filter. Alert fires at +100%, Emergency at +300%.

Daily running cost
Extra daily cost from filter clog — $0 means running clean
Extra daily cost = watts above the per-speed clean baseline × hours × $0.12/kWh.
Only accumulates on readings that crossed the alert threshold — money a timely filter clean would have saved.
Today is excluded since the day is incomplete. Update KWH_RATE in this file to match your rate.

Extra pump work
Watts above the clean-filter baseline — 0 means no extra work
Extra watts = actual power draw minus expected for a clean filter at that flow rate.
Expected is the 10th-percentile W/GPH ratio per 200-GPH flow bucket across all history,
so it adapts to each speed program independently. The line sits near 0 when clean, rises
as the filter clogs — unaffected by speed-program switches that used to dominate the chart.
