Anyone know about Sick pay

[MrsCarson]

Last week I broke my foot turned in a sick not heading off to fracture clinic the lot.
I'm trying to figure out how much SSP I get.
I work 24 hours a week but compressed into two 12 hour days. All I can see is based on how many days I work. But I'm working three days squashed into two days. Will I get less because of this?

I wrote sick not instead of Sick note

There's a calculator here
https://www.gov.uk/calculate-statutory-sick-pay

Looks like I get less for doing long days. Dam, I'll be dipping even more into savings.
I had thought it would be calculated using hours worked. Someone doing 24 hours over two days would get less than someone doing 24 hours over four days even though we earn the same
