heuristic, not a replay a strong heuristic for estimating the average dynamic-fee regime from candles, especially for volatile launches — not an exact per-swap fee replay. we pull the pump pool's 1m candles, approximate bin-crossings from each candle's range, evolve Meteora's v_a per the on-chain formula (hatchfun "1.00" preset: binStep 400, baseFactor 2500, vfc 7500, v_a×10⁴, cap 10%), compute per-candle fee rate, then scale to headline 24h volume. subtract Meteora 5% + hatchfun 20%, split buy/sell by 24h txn counts — sell-side fees (in meme token) are burned on hatch (shown in a separate column); only quote-side fees reach the creator. pump baseline = flat 0.05% prebond + 0.05% postbond creator fee.

limitations: candle-range underestimates intra-minute reversals; v_a decay is tick-spaced not swap-spaced; buy/sell ratio is approximated from txn counts; real hatch pools may use the "2.00" or "5.00" preset with higher base fees. volume is held constant though it would likely rise under tighter spreads — directionally, the number is a conservative floor for the volatile launches it targets.
