To quote one of my favorite watchmakers on RWI,
"I'd be more concerned about the amplitude and that looks good. The timing pics the TDs send are useless. You really need to show 4 or preferably all 6 positions at full wind and also after 24 hours. Only then will you know performance.
For instance. It could be +15s face up but -15s at crown down which will average out to 0 in real world. It will also slow down as it unwinds so +15 is probably worst case scenario."
