Clarke and his Phantom PR22 spooked his opposition with a stunning display at the Welsh circuit to win all four races and set a new series lap record at the venue in the process.
Added to three wins he had already snared earlier in the season, these latest triumphs have sent Clarke rising up 26 places in the winners' table.
He has reduced Mazda MX-5 ace Aidan Hills' advantage at the top to two victories and Clarke is only the second driver to score seven or more wins so far this year.
But there are a host of other contenders creeping up on Hills, including Radical Cup UK star James Lay.
He impressively won all three races as the category made its first appearance on the British Touring Car support bill at Snetterton, meaning the reigning SR3 champion jumps 30 positions and into fourth.
Another driver to enjoy a successful Snetterton was local racer Dan Zelos, who claimed two more Mini Challenge victories to take his current total to five and enable him to rise 31 spots to seventh.
Elsewhere, Lewis Thompson maintained his undefeated record in the Caterham Seven UK Championship at Croft with a hat-trick of wins to shoot from outside the top 50 last week straight into ninth place.
That is one position higher than Jonathan Lovell, who was another driver to enjoy MotorSport Vision Racing's Welsh visit as he picked up two Porsche Boxster Cup victories to improve by 39 places.
Revolution pilot Jonathan Mitchell jumps from 30th to 11th with Zeo Prototype Series success at Silverstone, while Radical SR1 ace Theo Micouris (12th), Brands Hatch Hot Hatch dominator Ryan Polley (13th) and BTCC conqueror Ash Sutton (16th) also enter the top 50 of the rankings this week.

All car races in UK and Ireland are included except qualification/repechage, consolation and handicap races. No races in other countries.
Class wins are only counted when there are at least six starters in the class. Only classes divided by car characteristics are included. Classes divided by driver characteristics such as ability, professional status, age, experience (for example rookie or Pro-Am classes) are not included.
Where there is a tie, overall wins take precedence. Where there is still a tie, average grid size for a driver’s wins determines the order.
