Powerduplicate in Designer and Photo copy differencies change perfectly

[MxHeppa]

Powerduplicate in Designer and Photo copy differencies change perfectly i mean when set ellipse x direction for example (happens all size values) change on px smaller first copies go fine but slowly there starts get little more like on 0.1px. only parameter what quick tests not get this problem is rotate.

Can you give a numerical example? ‘Power duplicate’ has never had an arithmetic progression option (which would allow e.g. 100, 80, 60, 40, 20). If you duplicate a circle of diameter 100 px and set the diameter of the the duplicate to 80 px, power duplicating will give you a geometric progression where each new diameter is 80% of the previous one: 100, 80, 64, 51.2, 40.96.
