A high-pass complement scan uses the same frequency and cutoff rows but shifts the kept budget toward higher frequencies instead of lower ones. The ratios are exact here only for the stated ideal transfer model and declared values; real high-pass circuits include capacitor and resistor tolerance, source and load impedance, parasitic paths, finite amplifier bandwidth and headroom, noise, temperature drift, and frequency/voltage measurement uncertainty.
The same frequency/cutoff rows show the high-pass complement without decimals. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

At cutoff the high-pass also keeps one half
The same cutoff row gives high-pass ratio 1/2 and output budget 10.
20⋅21=10
A higher cutoff blocks this low-index signal
With cutoff 12 hertz, the high-pass ratio is only 1/5. The output budget is 4.
20⋅51=4
A lower cutoff passes the same signal
With cutoff 3 hertz, the high-pass ratio is 4/5. The output budget is 16.
