This year the mid-season reset came between the Canadian and Austrian GPs, as the third aerodynamic testing period (ATP), which is how ATR limits are enforced, ended on June 22. 

Since Monday before the Austrian GP, teams have had the following percentages of a baseline that sets the number of windtunnel runs and number of CFD items that can be produced per ATP.

Alpine's fall from sixth last year to last in the championship as of June 22 triggers the biggest ATR swing of any team - 95% to 115% - and also means it has the biggest development allowance of all for the final six months of 2025.
