EIS Loss relief calculation

Hi
I'm making a claim for a total loss relief and I'm a higher rate tax payer at 40% through income tax deduction over two accounting periods 2022/24 & 2023/24. The investment was made more than 10 years ago.
Is it a simple calculation of being able to claim back 40% of the net investment?
Example:
Invested £100k
Tax relief £30k
Net Investment £70k
Loss relief £28k (40% of the £70k net investment)
Total loss £42k
I want to understand if it is a simple calculation as above or a complex one which takes into account personal allowance, basic tax rate at 20% and higher rate at 40% resulting in a lower loss relief.
