**Sweep** — Break the cold-pure Q-overshoot trap: pair aggressive thin-film geometry with WARMER/slightly-higher-ppm water to lower tank Q and series current, hunting the Td sweet...

**Sweep** — Attack 150 Td cold-window from the density side — cold low-ppm high-εr water pins f_r and raises N while wider gap/longer electrodes drop the field, co-swept with peak_...

**Sweep** — With cells cut to 1-2 (C_eff ~1.37nF), sweep the 3.7-5.5mH seam plus higher L to land f_r in the 32-50kHz band; hold coil Q high with realistic high-turn AWG18-22 coils...

**Sweep** — Hold the proven 3.7mH/12.9kHz neighborhood but push drive to 350V at low duty to lift V_cell/Td toward the deep CGDE window while keeping average draw safe and probing...

**Sweep** — Enforce the choke-L lever this time: sweep L 20-25x up from adopted 0.0001H to drag f_r from 304kHz toward 40-70kHz, while resampling turns/AWG for tank Q at the newly...

**Sweep** — Directly probe the L lever: sweep choke inductance widely (0.0001-0.0025H) to test if f_r honestly drops toward 40-70kHz, while co-varying turns/AWG to hold tank Q, wit...

**Sweep** — Force the high-L arm: pin chokes 8-10mH to drag f_r into the buildable <100kHz band with shrunken-C, while anchoring a fine grid at the 100µH current-best for score con...

**Sweep** — Bridge the gap left by both failed arms: sweep the mid-L 1.5-3mH region where C_eff=1.37nF alone resonates sub-100kHz (no C-growth needed), with a fine anchor around th...

**Sweep** — Drives choke L into 3-10mH so the fixed 1.37nF tank rings at 40-70kHz in-band; targets uncovered 3.7-4mH and 8-9mH windows plus a 100µH anchor for score continuity, hol...

**Sweep** — Push per-choke L into the ~0.95-2.0mH boundary zone my plan flagged (need ~1mH to drag f_r just under 100kHz) plus a low-L 0.12-0.25mH probe untouched by prior sweeps,...

**Sweep** — Unlock the untested 3.7-5.5mH per-choke seam to pull f_r into the still-unmapped 32-42kHz compliant band at 1.37nF, using high-turn realistic coils to hold coil Q>1000,...

Chris opened two levers on the desk (2026-07-27) and I built them into the design loop (evaluate() → drive-duty-v3): 1) DRIVE VOLTAGE (peakV). The loop was hardcoded to a 12V conti...

**Sweep** — 1-2 cell C≈1.37nF: sweep 3.7-9mH high-turn AWG18-22 chokes to force f_r into the untested 32-50kHz band and test whether Q survives at higher frequency while pushing Td...

This sweep confirms something I've been circling: at the 3.7mH/12.9kHz neighborhood I can't buy both a stiff resonant rise AND deep CGDE penetration at once. The tank Q is only 1.2...

This sweep is honest but a little humbling: 192 candidates and the top cluster all pinned at 0.379, which tells me I'm sitting on a plateau, not a peak. The refined score of 0.418...
