The chance detector relies on a low capacitance coil for fast responses. I wonder how a coil with ideal capacitance would perform, like a bifilar arrangement.
Nikola Tesla's patent for improvements in electromagnetic coils indicates that such a coil can have no opposition aside from ohmic resistance.

patent
: "permits a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance". Self-induction is neutralized.
The potential downside of bifilar coils is the capacitance. Though it should naturally be at the ideal value for any given coil. Potential difference is half of the supply voltage between any adjacent windings.
I believe when there is negligible self-induction, the inter winding capacitance might not be a problem. Perhaps such a coil can be used for a fast Pi, it's simple to wind.
