Please help to understand this sentence for tier 1 exceptional job

I found this" to the settlement you have to earn money in the linked-to your expert field during your most recent grant of global talent visa"

Does it mean during the whole three years I have to show I have earned money ?? or just like during let say last 4 months from my application to settlement?? it really confuses sentence to me. Your response much appreciate

"Evidence of currently working at an ‘exceptional talent level’. This does not need to cover the full three/five year period. We recommend the following evidence:

 A letter from your department/institution which confirms you are currently employed, dates of employment, your job title and your salary; and
 Your last 6 months of payslips"

This is for Tier 1 talent but mostly these are preserved in global talent visa as well.

Thanks a lot for the reply. It really gives me a clue.

Hello, I am curious as well in that if I work in the field for 2 1/2 years but for the last 6 months I might not be employed in my field (or at least not 100%) will that count against me.
