Three-times former champion jumps trainer Michael Dickinson feels he would need to write a book to fully explain what makes Willie Mullins so dominant.
Another stellar weekend for the all-conquering Mullins saw him win the biggest races on both sides of the Irish Sea, causing consternation within certain quarters of racing fraternity that his strength in depth is a negative for the sport.
Perhaps not since Dickinson saddled the first five home in the 1983 Cheltenham Gold Cup has National Hunt racing been in thrall to one man quite as much, with Mullins odds-on with the bookmakers to be champion trainer in the United Kingdom and in Ireland.
Having dominated the Cheltenham Festival for four of the last five years, Mullins is currently responsible for 11 ante-post favourites for the March jamboree - and in many of those races he also trains the second and third horses in the betting.
Dickinson, now training in America again, says Mullins' rise to the top has not happened overnight.
He told Press Association Sport: "I always found it tough to beat Fred Winter and Peter Easterby so never went to Cheltenham thinking we were going to win, just like Willie won't.
"Finding all these good horses at the same time is not something you can put into a sentence, you could write a book about it.
"I know Willie well. He's a nice man and deserves his success."
While he may now dominate his profession, Mullins was relatively unheralded back in 1995 when the Mark Dwyer-ridden Tourist Attraction landed the Supreme Novices' Hurdle to give the trainer the first of 41 Cheltenham Festival winners.
"You couldn't see it coming," Dwyer said of the County Carlow handler's ascent.
"With Willie, it's a case of what he doesn't say, rather than what he does.
"That day with Tourist Attraction I was stood in the ring with him for three of four minutes making small talk, waiting for him to give me some instructions when he just said, 'Ah, you know yourself".
"I'd ridden for his father (Paddy) as an apprentice which is why I possibly got the ride.
"His dad was a very shrewd man, way ahead of his time, and he's obviously picked up things along the way - the whole family is steeped in racing.
"No one could envisage the position he's in now, though. He's got a good supply of horses but that's stating the obvious."
One of Mullins' latest superstars is Un De Sceaux, winner of the Arkle last March and scintillating in the Clarence House Chase at Ascot on Saturday.
He is owned by Edward O'Connell and his son, Colm, said: "Every call Willie makes is proven to be the right one.
"When we didn't go to the Champion Hurdle with Un De Sceaux two years ago, Willie said he wasn't mature enough and look at him now.
"It was 100 per cent the right decision. These are brave calls to make, like when he decided not to run Un De Sceaux in the Tingle Creek because he wasn't totally happy.
"The key to his success is he trusts his team implicitly. Ruby (Walsh), Patrick (Mullins) and David Casey all play a huge role, along with Willie.
"They call the shots and all the owners are happy to go along with it. Why would you interfere with what they are doing given their success?
"What they are really good at is not dwelling on the negative.
"When Un De Sceaux fell at Christmas, the talk wasn't on what might have been.
"We'd missed out on a Grade One but straight away the Clarence House was mentioned, and that worked out.
"They've always got a plan, they never dwell and they always accentuate the positive.
"It's an absolute privilege to be involved with them.
"Watching the races, Willie is ice-cool - you'd have no indication of what he was thinking - yet after the race, once we've congratulated each other, he starts asking if we've eaten and what our travel arrangements are!
"We're just there at the right moment, on the right trajectory, and we're caught up in the storm."
