Maximum number of splits will occur when u follow left biasing with right median as here the keys are not coming in an ordered way, i.e. keys are not decreasing or increasing.
1st leaf node split: insertion of 40
2nd leaf node split: insertion of 35
3rd leaf node split: insertion of 20
4th leaf node split and 5th internal node split : insertion of 8
6th leaf node split: insertion of 10
7th split leaf node split and 8th internal node split: insertion of 5
So total number of splits=8
