NHS Bursary entitlement for 5th year

Hi guys, I have posted this somewhere else but just reposting as this is a better-suited forum.

I'm applying for NHS bursary which we are entitled to in our 5th year of medical school.

Just trying to get my head round this pdf: NHS Bursary Funding for Medical and Dental Students 2022-23 (nhsbsa.nhs.uk)

I understand you get a non-means tested bursary of 1k which is fixed for every student. But on top of that, in my case as a student outside of London living in accom, I am eligible for up to 2.6k extra (means-tested bursary) which is based on my parents' income.

Can anyone explain this pdf and what the max parental income is before you are no longer eligible for this means tested bursary (is there a cut-off?). Think it's explained on p.19-20 but just wondering whether it's worth applying for it since it's gonna be a lot of paperwork for my parents. Ik obviously there's other factors to account like pensions, your parents' expenses etc., but just want to get an idea of it.

Thanks!!
