First Michael Cullen and then James Clarke had trimmed the gap to Slater but it now stands at four victories again after his 15th and 16th triumphs of 2023 at Cadwell Park.
However, it was not a clean sweep for the teenager in Lincolnshire as he stalled and subsequently retired from the finale - which also meant he missed out on the chance of clinching the title with two events to spare after a truly dominant season.
But Slater is not the only driver towards the summit of Autosport's winners' table to have boosted their score after last weekend's race meetings.
A driver on the rise is Aidan Hills. The Mazda MX-5 star topped the table earlier this year but had slipped down to sixth prior to his two MX-5 Supercup victories at Snetterton, which have sent him back up to third.
Alongside Slater's dominance, the wins in the other Ginetta categories also have not been widely distributed and 10th and 11th GT Academy successes for Ravi Ramyead at Cadwell have propelled him from 10th to fourth in the rankings.
The other race was won by his title rival Nick White, who in turn climbs three places up to 15th.
Ginetta GT leader Luke Reade only added one more win to his tally, but it was enough for him to gain one more place to climb to eighth.
Over at Snetterton, Steve Foden also made a similar rise to sixth after also taking one MX-5 win among the Mk1 contests.
