Verification of Atlantic ghost storm tracks of August-October 2019

I falsely detected (sub)tropical cyclogenesis in Atlantic (north of equator and west of Greenwich) 56 times in August thru October of 2019. Tracks were made of 23 systems.

At the lead time of 1 day (24 hours), there were 0 false detections.
At the lead time of 2 days (48 hours), there were 0 false detections.
At the lead time of 3 days (72 hours), there were 3 false detections.
At the lead time of 4 days (96 hours), there were 4 false detections.
At the lead time of 5 days (120 hours), there were 5 false detections.
At the lead time of 6 days (144 hours), there were 7 false detections.
At the lead time of 7 days (168 hours), there were 10 false detections.
At the lead time of 8 days (192 hours), there were 11 false detections.
At the lead time of 9 days (216 hours), there were 13 false detections.
At the lead time of 10 days (240 hours), there were 17 false detections.
At the lead time of 11 days (264 hours), there were 23 false detections.
At the lead time of 12 days (288 hours), there were 27 false detections.
At the lead time of 13 days (312 hours), there were 27 false detections.
At the lead time of 14 days (336 hours), there were 29 false detections.
At the lead time of 15 days (360 hours), there were 28 false detections.
At the lead time of 16 days (384 hours), there were 32 false detections.
