Ford Focus and Fiesta pilot McGill has been in impressive form of late and followed up his double Focus Cup win at Oulton Park the previous week with two Scottish Fiesta ST Cup triumphs at the Scottish Motor Racing Club's 'away' trip to Cadwell Park.
Those victories take McGill's 2022 tally to 11, moving him up from seventh to become Khera's closest challenger.
The only other change inside the top 10 of the rankings also concerns a driver winning in a Fiesta ST: Michael Cullen.
He picked up a win at Mondello Park in his Ford, having taken the lead from his son Victor.
Cullen Sr also defeated his son in both of the Irish Stryker races to take his total to nine wins for the year and enable him to jump up from 37th to eighth in the winners' table.
Also scoring a hat-trick in Ireland was Geoff Richardson in the Legends category, those triumphs enabling him to move from outside the top 50 straight into 17th place.
You then have to go down to 28th spot to find the next position change, courtesy of Ric Wood - another driver outside the top 50 last week.
He scored a double win in the Historic Touring Car Challenge at the new Snetterton Historic event in his Nissan Skyline as a pair of the Japanese machines enjoyed a scrap with a trio of Ford Sierra RS Cosworths.

Two places behind Wood is Michael Weddell, the Scottish Minis ace being another double victor at Cadwell who joins the leaderboard, while Scottish Classics Rover pilot John Kinmond similarly moves into 38th position.

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.
