But he would be even happier if he was not giving some very smart horses a head start.
The 5yr-old starts the 2700m journey at Ascot Park 40m behind the front line - but more importantly, he is 10m behind Isaiah and 20m behind Meticulous, who represent two very strong chances for the Mark Purdon and Natalie Rasmussen stable.
Belkmyster has earned just under $70,000 from his 42 career starts - a pittance compared with the $498,470 collected by Isaiah in 29 starts, including 11 victories.
However, the vagaries of the handicapping system, which include 3yr-old concessions, means Isaiah is classed as a seven-win horse and Belkmyster, who picked up one penalty-free win as a 3yr-old old, is an eight-win horse.
The son of Mach Three almost became a nine-win horse, courtesy of the group 3 Central Otago Trotting Cup at Omakau on January 2, going down by a neck to Jason Rulz.
''It was outstanding,'' Anderson said of Belkmyster's second placing.
''He hadn't been pacing the best so we got a bit of physiotherapy done. He had a pulled muscle down the near-front leg coming from the wither - we fixed that up and he paced beautifully. He was a whole different horse there.''
A note in the stipendiary stewards' report provided punters with another reason to be impressed by Belkmyster's placing in good company.
''He probably would have won but he got a punctured tyre at the 300m and it wrapped around his wheel, so that probably cost him the win, to be fair,'' Anderson said.
''It was a bit unfortunate, really.''
The bonus for Belkmyster at Omakau were the conditions of the race, which gave him an even chance.
''It's very difficult to find the right race for him. That race at Omakau was perfect for him - a mobile free-for-all,'' he said
"He's 40m behind [tonight] and in the Invercargill Cup he's 40m behind, so now they've let those handicaps out a bit it's made it harder for those horses. I've got to get the right run with him so we're looking for someone to get going with a round to go and put us into the race.''
Belkmyster's last public appearance was at the Forbury Park trials on Saturday where he and Smokin Bird went to war in the closing stages to pace the 2200m in 2.44.0.
''He bowled around there, then Coxy [Jonny Cox] attacked me at the 600m. That's why we went so fast,'' Anderson said.
''We were going to go about 2.49 but they got off and got going. The track was beautiful and it was a beautiful day and realistically that's what those horses - if they're going to compete in these races - are going to have to go, so it was a good hit-out and he came through pretty well.''
Isaiah and Meticulous are joined at the Northern Southland meeting by stablemates Take To The Sky (race 8) and Someardensomewhere (race 10), along with Derby-winning trotter King Denny (race 9), who makes his season return in the group 3 Southern Lights.
Anderson said Titan Banner was having a six-week spell after not coping with a hard Roxburgh track. The 3yr-old is likely to return for winter racing.
Northview Major is back in work after picking up a cold, while Starsky's Dream will start work again this week after finishing ninth in the Gore Cup.
