What this ISCO Championship page covers

This is the permanent page for the ISCO Championship as an event, not for any one year of it. It lists all 11 editions OTIS holds — 2015 to 2026— with the winner, the winning score as the tour published it, the host course and the number of players who started. Every row links to that year's own page, which carries the complete final leaderboard: every player in the field, their finish, their four round scores and their total. The most recent edition is linked at the top of this page rather than reproduced here, so the two pages answer different questions instead of the same one twice. Nothing on this page is estimated: where the tour published no value — a winning score for a match-play week, say — the cell is a dash.

How OTIS decides that two years are the same event

Sponsor names change and event names change with them, so grouping by name would split one tournament into several. OTIS groups on the tour's own event code instead — the last three digits of a tournament id, which the tour keeps stable across every rename. That is why the 11 editions here appear under 2 different names, and are still one event. The one adjustment is the tour's 2023 calendar restructure, which issued a second code to six events that already had one. Those six are rejoined by an exact rule — the two codes' current names must normalise identically and their sets of years must not overlap — never by a name resemblance. It finds exactly those six pairs in the published data and no others.
