The cause of the AI getting randomly slow

Product: EA SPORTS™ WRC
Platform:PC
Summarize your bug Unfortunately, there is still a problem with the difficulty level of other drivers in solo mode in the championship. I set the level to 80% in Monte Carlo, I rode the first stage and finished it in 3rd place with a loss of 5 seconds. Cool. I drove the second stage and unfortunately I finished it first with an advantage of 30 seconds over the second driver. I rode the second section in a similar style to the first. I still rode the remaining few sections with an advantage of 20-30 seconds. I think I was in 7th place in one episode. There is a big problem with the difficulty level, which kills realism in this game, and I abandoned my championship after the 11th stage in Monte Carlo because I gained a total of 3 minutes over the second driver. I increased the difficulty to 100% and it didn't change anything. And I'll add that I use a keyboard... Please, EA, improve the difficulty level in solo competitions in your own championships.
