The $377,065 the Matamata horseman has won for his stable since August 1 is just shy of the $382,435 he scored last season.
Richardson is on a winning curve, but the success gets the attention of others a lot more than it does Richardson himself.
"When you look at those season totals you have to realise until a couple of years ago, I had half my team in Australia and half here.
"I used to train 14 or 15 here and 16 or 17 in Australia (Melbourne)."
A number of New Zealand trainers have tried that exercise and gave up, deeming the dual-country approach just too tough.
Not Richardson.
"I actually loved it, I miss training in Australia.
"I'd go back to doing the same thing tomorrow, but my Australian owners wanted me there full time and my New Zealand owners wanted me here.
"The Australians made a concerted effort to get me to move over there permanently, but I said no. I told them my home is in Matamata and that's where I want to live.
"Your family always has to come first."
Building horse numbers back up at home from the meagre levels of the dual-country training is not an overnight thing. "It took time to build up the clientele again.
"And when you buy yearlings it can be a couple of years before you see the fruit of what you've done."
Richardson sees his recent success as the payday for that three-year exercise.
He was more excited on Saturday for Masa Tanaka than he was for himself. Tanaka served his apprenticeship in the north with Graeme Rogerson and moved to the central districts a couple of years ago.
To provide more opportunity, he recently moved north again to link up with the Richardson stable, for which he rode Green Wings and Jubilate to victory on Saturday and Allanah at Te Rapa last Thursday.
"Masa is the country's most underrated rider," said Richardson.
"He gets on well with Green Wings and did a great job to get Jubilate home by a nose in a fight with James McDonald. Masa is going to go from strength to strength from this point."
James McDonald rode the third Richardson winner Positivenergy, a horse the trainer would like to see if he can get into the Derby line-up in March.
"I know he's a bit behind the eight ball, but we'll keep thinking that way. Who knows."
Richardson won the City Of Auckland Cup with Single Minded and has the favourite, Green Supreme, in the Wellington Cup.
* David Walsh has once previously ridden six winners on a day to match the half dozen he booted home on the West Coast on Saturday.
"It was at a Wairoa Cup meeting somewhere in the late 1980s, but I can't remember the date," said a very satisfied Walsh from his base in Christchurch yesterday.
And five in a day has happened so often he can remember only one of them. "One day I took only five rides and they all won."
Perhaps remarkably, Walsh is riding as well as ever in his 50s.
His fitness is legendary and so is his judgment of pace, something that used to be compulsory and is now quite rare.
Watching Walsh on a front runner is beauty itself.
Whether the horse wins or not, he will have used pitch-perfect pace, tailored to the conditions and the opposition.
If the horse doesn't win with Walsh aboard and in front, it wasn't good enough.
