Bogey-Free Round Probability Calculator

Start with the market definition

For Bogey-Free Round Probability, bogey-free probability combines Expected bogeys or worse and Course and weather adjustment into a first-period scoring expectation, with the next visible input reserved for the pitching, venue, or matchup adjustment shown on the form.

Formula: bogey-free probability = e^(−adjusted expected bogeys).

Market context

On this page, field strength, course fit, tee time, weather, and starting status should match the tournament being priced.

Entries required for the result

Treat golf matchup as a follow-up handled by Golf Matchup; compare results only after matching participant and period.

Change one assumption at a time

Hold the line fixed and lower Expected bogeys or worse in a separate case.

Revise Course and weather adjustment independently so causes remain distinct.

For this comparison, a close result should survive a plausible lower-scoring case.

To compare first-round leader separately, open the First-Round Leader after saving this baseline.

As a practical check, use the output as decision support and keep personal limits outside it.

Limits of the estimate

Hole outcomes are compressed into a Poisson count.

On this page, review dead-heat deductions, place terms, cut rules, ties, and whether the wager covers a round or tournament.

Within this calculation, correlation, selection bias, and small samples can remain when every field has a source.

What to preserve with the calculation

The strongest comparison keeps model inputs and market information in different columns. Record Expected bogeys or worse and Course and weather adjustment as assumptions, then record the quoted line or price with its timestamp. This prevents a later market move from being mistaken for a change in Bogey-free probability itself.

Look for dependency between the visible entries. If Expected bogeys or worse was already used to construct Course and weather adjustment, applying both independently may repeat the same information. Calculate the simpler version first, add the disputed adjustment in a second case, and compare the two values of Bogey-free probability.

A boundary check should cover realistic low and high values for Expected bogeys or worse, not arbitrary extremes. Hold Course and weather adjustment steady during that test. If Bogey-free probability crosses the relevant line throughout a defensible range, the conclusion is sturdier than one supported by a single point estimate.

Document why Expected bogeys or worse belongs in this calculation instead of merely recording its number. A short reason—role change, venue effect, price quote, or observed rate—helps another reader understand how it relates to Course and weather adjustment and why Bogey-free probability changed from the baseline.
