Flock scored an 11th win of the season in the opening race in Norfolk and, despite a spin in the second contest, he threatened main rival Cameron Pratt-Thompson but could not quite find a way through to score another triumph.
Nevertheless, he still improves on the leaderboard moving into ninth, and is now five wins shy of the tally of table-topper Freddie Slater - the Ginetta Junior ace impressing on his British Formula 4 debut at the weekend.
But Flock was not the only driver inside the top 10 to add to their total following the bank holiday weekend's events. Lucas Romanek profited from a clash between his fellow Castle Combe Formula Ford 1600 frontrunners Luke Cooper and Josh Fisher to triumph in the opening race.
However, with some of the FF1600 fields he has headed this year containing very few cars, he remains in fourth place, unable to leapfrog James Clarke and Ryan McLeish - who are also on 14 wins but have achieved those with a higher average grid size.
While Romanek's sole victory did not improve his position, a win for British Touring Car dominator Ash Sutton at Donington Park meant he certainly did.
Not only did the success draw him level with BTCC greats Yvan Muller, Alain Menu and James Thompson in sixth place in the BTCC all-time most wins list, it also means he gains seven spots in Autosport's 2023 winners' table and moves to 14th.
You then have to go all the way down to 27th position to find the next improver: Bikesports master Charles Hall.
The Mittell pilot bagged another two wins at Brands Hatch to rocket up the leaderboard having been outside the top 50 last week.
Another driver to succeed at Brands was Bryan Bransom, who joins Hall on eight wins for the year after triumphing in one of the BMW Car Club Racing contests - a victory that sends him from 40th to 30th.
