Both the Scottish and Irish Legends categories headed to Wales for a combined event and McLeish was one of several drivers to enjoy success at Anglesey.
His three wins have taken his 2023 tally to 12 and have catapulted him up seven places in Autosport's table.
Stewart Black narrowly denied McLeish a fourth victory in the opening heat on Sunday and that success has in turn allowed him to jump up four positions and into 12th.
Meanwhile, Peter Barrable twice topped the Irish contingent to improve his own ranking by 13 spots and is now one place behind Black.
McLeish has a further chance to narrow his deficit to table-topper Freddie Slater this weekend as he has entered the Knockhill round of the British Touring Car Championship-supporting Legends Elite Cup.
But, while the Legends drivers are gradually closing on Ginetta Junior dominator Slater, Formula Ford 1600 frontrunner Romanek is now his nearest challenger.
Romanek's latest triumphs came in the United FF1600 category at Snetterton, where he trounced limited opposition to win both races.
As well as propelling him from fifth to second in the table, the success means he is now just three victories behind Slater's 16.
Michael Cullen was another driver to add to their haul at Anglesey, although he just picked up the one win compared to the four he has achieved during recent Mondello Park events.
He won the Stryker opener but was narrowly defeated by son Victor in race two, although Cullen Sr still gained one spot on the leaderboard as he moves to fifth.
Further back, Andrew Graham continued his impressive run of Scottish Classic Sports and Saloons form in Wales.
Although he was racing an MGB rather than his usual Triumph TR8, Graham still added a further two wins to jump up 21 places, climbing to 18th.

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. Each race counts only once, so an overall winner’s class win is not added.
Where there is a tie, overall wins take precedence. Where there is still a tie, the average grid size for a driver’s wins determines the order.
