Hello,
The rate of training is dependant on the gap between the driver/pitcrew
(D/PC) level and your manager level.
As the
D/PC level increases, the rate of training will decrease.
If you train the
D/PC to a level which is higher than your manager level (which will be
indicated by red stars), training will hugely slow down, to just 3% per 1x training.
The star level of your Team Doctor also has an impact on the rate of training. Section 10B of the
2022 iGP Manager Guide contains further information on Doctors and their affect on training.
Another factor in the rate of training is your Simulator Headquarter - the impact that your HQ level has on training is indicated within the Simulator HQ page.
I hope this helps. If you still think your rate of training is too high, please record a video so we can take a look and confirm whether there is an irregularity.
Thank you.
