You develop a ChatGPT prompt and keep it going so it keeps your constraints in memory. (That said, GPT convos are limited to a certain length so you need to restart once in a while.) My initial prompt looks something like this right now:
I bet on hockey and need to compute win probabilities for every NHL game tonight. To do so, use hockey Elo ratings for each team, apply a form correction for the last 10 games played and take injuries into account along with starting goalies. Express the probabilities as a percentage AND as a moneyline in US format, and only give me probabilities for the favored team along with the name of the favored team. Be concise - I don't need a full writeup for every game, just the probabilities and the favored team's name. Do all of tonight's NHL games, which are Blues at Hurricanes, Capitals at Golden Knights, Rangers at Kraken and Predators at Canucks.
