Parlay combiner FAQ
- Is this a guaranteed parlay or “lock”?
- No. Ban language: locks, guaranteed parlays, invented sportsbook lines. This is product-of-probabilities math under an independence ASSUMPTION.
- What if legs are correlated?
- Correlation breaks the product math. Treat outputs as literacy scratchpad only — verify on the venue and never treat ChanceWire as a ticket.
- Do you invent live sportsbook or Kalshi lines?
- No. You type each leg. Kalshi/Novig stay Not listed. SoftCta educational only.
- Where else can I practice odds math?
- Odds comparator and break-even calculator reuse the same SoftCta converter posture.
- Is this financial advice?
- No. Math only. SoftCta /r / AgeGate locks stay unchanged.
