I tried Comskip several years ago and it was useless! It missed some adverts and detected adverts where there were none!
In the UK depending on the channel and time the adverts last around 4-5 minutes. In KODI I have skip set to +60 and -30 seconds. At the start of the advert 4 quick skips forward and if the adverts are still running a 5th skip. If the adverts have finished a skip backwards. So sometimes I see up to 30 seconds of adverts which I put up with for a simple solution!
