What moves it most

Upset watch: the model still gives 42% to the underdog. Two fights in five at this price go the other way.
Limited data: at least one of these fighters has a thin or uncertain record, so treat this prediction with caution.

Summary

This prediction rests on one fighter only. We have no UFC record for Ko Seok-hyeon — no bouts, no style profile, no date of birth and no reach — so the model is comparing Wellington Turman against the welterweight prior, and Turman is the pick at 57.7%, against 42.3% for Ko. The three factors the model names are all artefacts of that absence: the rating difference, the UFC-experience gap and the difference in rating certainty. Turman himself is not in form, with three straight losses before a 34.8-month layoff and a rating of 1685 that ranks him 71st at welterweight. His profile is close to the division average across the board, with 49.2 significant strikes landed per 15 minutes against a 48.3 average and 195.0 seconds of control against 189.1. Treat the 58.3% as the division prior plus a layoff, not as a read on this fight.

Full analysis

Turman is an average welterweight on every rate we can measure, which is the most useful thing to say about him. He lands 49.2 significant strikes per 15 minutes against the 48.3 division figure and absorbs 56.6 against 54.6; his 51% striking defence and 44% accuracy are both at the norm. On the mat he attempts 4.6 takedowns per 15 minutes at 33% accuracy against division averages of 4.2 and 34%, and holds 195.0 seconds of control against 189.1. The two numbers that stand out are his 54% takedown defence, below the 58% average, and the 246.3 seconds of control he concedes per 15 minutes, which is at the division's 247.0 — he is takeable and he does not get up quickly, with 0.16 reversals per 15 minutes against a 0.20 average. His last five are two wins and three losses, the most recent a second-round submission to Jared Gooden in December 2023. For Ko Seok-hyeon there is nothing to report. The database holds no completed UFC bout for him, so there is no style profile, no rating and no age, and nothing about his striking, grappling or pace can be stated. This analysis will not guess at it. What that leaves is a fight the model should not be read as having an opinion about. Turman's 57.7% is built on having a measurable record at all, and the 34.8 months since he last fought is itself a penalty the model applies rather than evidence about his current form — he was 0-3 before he stopped. The one concrete thing in Turman's numbers that would matter against any opponent is his defensive grappling: 54% takedown defence and 246.3 seconds of control conceded per 15 minutes are the weakest parts of his profile, and a debutant who wrestles would find them. The model gives 48.1% for a decision and 34.6% for a knockout, but with one side of the fight unmeasured those method numbers are the division's shape rather than this bout's.
