[irshadaj]

Description

• Improved code readability by using better suited data types in query complexity calculations
• Fixed missed loophole in query complexity calculation
• Refactored reduction factor into its own function to aid readability

How Has This Been Tested?

Changed code paths are under extensive unit and integration tests, which had to be updated accordingly.

Just one question on a test condition changing to better understand. Otherwise, this all looks as expected
