My approach was to utilize Both especially for single tooth and manual kikstarter, to be ready on both sides of blind. But unfortuneally, my experiments show me the Trigger can't become syncronized by 'last' and folowed 'first' events only. Also I observe phase-aligment mehanism is trying to consume a longer side of trigger as latest before TDC. I wish to setup SyncEdge::Both for my TT_60DEG_TOOTH after this case of scenario become work well. For now, Rise work well for my 60 degree trigger and both edges phase sync work as mush as expected for my engine startup.
