The deck does not reset. Every card that turns over changes the correct price of the next one — and the quoted odds do not always keep up.
Start the Next Card Pricing drillFree, runs in your browser, nothing to installThe true probability is simply qualifying cards remaining ÷ cards remaining. At the start, the chance the next card is a heart is 13/51 after one card is showing. Once four hearts are gone, it is 9/47.
The discards stay face-up on the table. Everything you need is visible; the question is whether you are tracking it while also pricing.
The quoted odds are generated from the true probability multiplied by a random factor, so sometimes they are generous and sometimes mean. Counting the deck perfectly is worthless if you then take a poor price.
The discipline being trained is holding two things at once: a running estimate of fair value, and a judgement about whether the price on offer beats it. That is the job.
Do not try to remember every card. Track the one or two categories that matter for the event being quoted — how many hearts have gone, or how many high cards remain.
Keep a running count rather than recounting the discard row. Recounting costs time you need for pricing, and time pressure is where errors enter.
