But as this teenager has repeatedly demonstrated over the last couple of years, he has a maturity beyond his years on a golf course.
His game is pretty remarkable, too.
When you might expect juniors to want to be flashy and expansive, Chedhomme’s game-plan is very simple – hit it straight, find fairways and greens, then putt well.
Sounds easy and he makes it look it, but if it was there would be far more golfers in Guernsey playing off the 1.9 handicap he is now down to, but there are not.
In those terms, the Island junior champion arguably went into the LGM Club Championship as the favourite and he had no problems carrying that extra burden on his young shoulders.
Two quality rounds later, he had posted a gross three-over-par aggregate of 133 that no-one even came close to matching.
Having just shaken hands with previous champions Dave Jeffery and CJ Elmy on the 18th green with a seven-stroke victory in the bag, Chedhomme’s smile eventually betrayed his emotions.
‘It’s very high [on my CV], one of my biggest achievements for sure, probably the biggest so far,’ said the 15-year-old.
‘I’m very happy with it.’
Chedhomme’s one-under-par 129 nett aggregate saw him finish top of those standings, too, one shot ahead of Banks and Halden.
In the women’s event, multiple former Island champion Jan Chamberlain added another title to her collection with a 162 gross aggregate, having established a six-shot lead on the field with an opening 77 that included three birdies.
Ali Brown’s 82 gross was the best round of the second day and lifted her to second place in the final standings.
She was also second in the nett leaderboard, finishing on 140, two shots behind the LGM lady captain Bobbie Odoli who had an outstanding 65 nett on Sunday.
