Hi Prema,
It will be like this, you need to see each country lies in which band and for that period you need to earn on prorota basis
Exp. Country 1 Earned - £6000 (for 4 months) , it falls in band x
if you would have earned the same salary for twelve months then it would be £24,000.00
£24,000 for band x - falls in category 2, points earned would be - 30
Lets say under similar calculation for Country 2 - under band y - you would have earned - say 40 points
and for Country 3 in band z, - 50 points
Now your net points earned in earning is 30 + 40 + 50 / 3 = 40 points
Hope this is help ful.
best wishes
