That pair of victories not only netted him the title again but also sent him to 16 wins for the year, level with our table-topper Ryan McLeish. However, a smaller average number of starters for Cullen's victories means he only climbs from fifth to third.
He was also in action in the Fiesta ST series and, although he wrapped up another crown, he was beaten in both races and therefore missed a golden chance of moving into first place in the winners' table.
Away from Mondello, there is only one other change in the top 10 of the rankings following last weekend's action and that comes courtesy of Callum Grant.
He twice defeated Benn Simms in thrilling Silverstone Historic Formula Ford 1600 battles to take his 2023 tally to 13 and he was also in the thick of the Classic FF1600 fight but could not quite add further success. Grant therefore has to settle for a gain of 11 places to move to ninth.
Both of the Historic FF2000 victors are other drivers to move up the table. Champion Graham Fennymore won the Silverstone season finale to take his total to 11 wins for the year and enable him to leap seven spots to 16th.
The opening race was claimed by Historic F3 title winner Samuel Harrison on his series debut. That success, combined with class honours in a shared Brabham BT5 in the Guards Trophy, have sent last year's rankings leader from 47th to 29th.
The two Oulton Park Kumho BMW conquerors are also notable movers this week. Jason West took the second win in a red-flagged contest to jump six places to 19th.
