Something may be affecting the VFB voltage seen at the Nano (artificially making it higher than it should be) which causes the code to reduce the voltage to be in balance again. To be honest I am unsure but suspect the % modulation should change lower due to the artificially increased VFB. where as it should have gone to a higher % for losses due to system current/voltage drops or transformer/choke influences.  I love servo loops.....
