Happy new year to all the members!

I am currently in the UK for over 9 months on a Work permit from an Indian company. I am planning to apply for my HSMP very soon, probably in the next 2 weeks.
Since i have earnings both in the UK as well as India, and having read the HSMP guidance form, i understand that my application would be considered on prorata basis since i have spent 9 months in the UK and 6 months in India over the past 15 months.
1. For the sake of reaching the prorated figure, I have summed up the Gross Salary I received in the UK over the past 9 months and multiplied it by 12 and then divided it by 9. This gives a figure of 30,648 GBP.
As per my Company, my Gross Salary is 31,620 GBP.
Would this be an issue while the case worker works on it since the figures dont match? Ofcourse, prorated and actual figures never match, but how should I explain this to the case worker?
2. This figure of 31620 pounds also contains a part of Indian salary which is 3450 Pounds, since i have chosen the option of taking the Indian salary in the UK. Also, I am paying tax on the whole figure of 31620 pounds. Even my company has clarified to me that my Gross Salary for all practical purposes would be 31620 Pounds.
I am bit skeptical about it since there is a part of Indian salary in it as well, and wondering if the case worker might find an isue with it. Can someone please advice on it?

Warm regards,
FC.
