But as Southland's opening meeting of the new term gets going at Ascot Park tomorrow, Williamson has his sights set on a new season-best after his 42 wins in the 2014-15 season.
The 42 victories - starting with Nickelson last August and wrapping up with Kiwi Focus at Forbury Park in June - broke the province's previous best of 35, set by Williamson in 2012-13.
So why not shoot higher this year?
''You aim to, as long as you keep improving,'' Williamson said.
The rising star of the training ranks expected last season to be a good one, based on the groundwork he had done in 2013-14.
''I had a lot of nice 2yr-olds [in 2013-14] but I didn't race a couple of them and held them back as far as racing was concerned. Tas [Man Bromac] had one race, Statham qualified but didn't have a race and I thought last season they would do a good job.''
So it proved with Tas Man Bromac winning six races and almost $50,000 in stakes last season, and Statham grabbing four wins.
''I cut the numbers back and worked a lot more coming through for that in-between season. So this season that has just been, I knew I would be able to have a strong season, which is good.''
A pair of lightly-raced pacers could be the ones to get Williamson off to a good start this season.
Polperro Bay had just one start for Williamson last season, finishing fifth on debut at Ascot Park on June 1.
The 5yr-old is in a nine-horse 1700m fillies and mares' mobile pace, and Williamson expects improvement from her June performance.
''I was rapt with her run on debut considering she had only had one qualifying trial before that,'' he said.
''She was pretty underdone experience-wise and fitness-wise.
''It's not a big field . She's got a tricky draw but I'm quietly confident she'll be pretty tough.''
Gangnam Style (race 9) is a replacement for Onedin Mach's owner, Neville Cleaver, who sold his well-performed pacer to the United States.
Gangnam Style had a start from Colin and Julie De Filippi's stables last week before joining Williamson this week.
''He's come down here to have a few runs and, hopefully, recoup some of his money before he goes for a break,'' he said.
''I'm quite impressed with the horse. I think in time, he'll develop into a nice wee horse.''
Dwindle Mist (race 4) faces a tough task off a 50m handicap in the 2700m trot.
''I expect Dwindle Mist to be a run short.
''With a couple more runs under her belt, I would say she would be extremely hard to beat in that field.
''We'll just tack on and see if we can get a nice run into it.''
Williamson has made some minor gear alterations with Grey Fernco (race 2), after she recovered well from a break to finish fourth at Oamaru on Sunday.
''I think she's still a wee bit claustrophobic,'' he said.
''I chose to go up the inside of another runner and she shied away from it and galloped.
''It wasn't really her fault. With the right run, she should be thereabouts.
''She hasn't trotted the best at Invercargill so that's a wee question mark.''
Williamson said Lis Is Fine (race 3) was the best of his drives for other trainers.
