Different duplicated_lines_density with SQ 7.5

Hi,

we did some first tests with SQ 7.5 and get different duplicated_lines_density values. Is this a bug or a feature?

Feature: Smoketest
  Scenario: Smoketest 
    Given the project "smoketest_project"
    
Assertion Failed: 
      	duplicated_lines_density is actually 45.7 [expected: 55.6]

Regards,
Günter
