Slater has been the class of the Ginetta Junior field this year, utterly dominating the opposition and winning seven of the nine races to date.
But it could easily have been a 100% success record, had Slater not received track-limits penalties in one race at each of the Silverstone and Donington events.
Nevertheless, he has still shot up Autosport's winners' table, rising five places into third.
And, with six races as part of Ginetta's G Fest meeting at Silverstone this coming weekend, there is the potential for him to now usurp Aidan Hills's nine wins at the top of the rankings.
Reade has also been the standout star of the Ginetta GT Championship in his G56, although his 100% record was broken at Donington when a suspected driveshaft failure on the grid left him as a non-starter. But his other two Leicestershire triumphs still enabled him to leap from 25th to sixth.
That is one position higher than one of the other notable movers of last weekend, Northern Irish Sevens racer Graham Moore.
He scored another two victories at Kirkistown at the wheel of his self-built GMS machine to take his tally for the year to six and enable him to climb 25 places.
Lucas Romanek is the next highest-placed improver having scored a National Formula Ford 1600 win at Snetterton to jump up 11 places to 12th as he continues his campaign across three FF1600 championships.
Two more drivers to enjoy successful Donington weekends are Ravi Ramyead and Tom Mills.
Ramyead took the spoils in two of three Ginetta GT Academy contests to move to five wins for the year - enabling him to jump from outside the top 50 and into 13th.
Mills has made a similar surge up the order after winning three of the four GB4 Donington bouts to continue his strong start to the season and also move into 14th on the winners' table.
Also moving into the top 20 are two drivers to enjoy success at the Brands Hatch Masters Historic fixture: Chris Beighton (Lola T70 Mk3B) jumps 11 places to 17th and Nigel Greensall (in both a Ford Capri and TVR Griffith) is another new entry in 20th.

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, and 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.
