Not needed? Rated 2 out of 5 stars

I don't understand why I need this to sync Google calendar & Lightning. I can put the GCal link in "New Calendar"... can't I? (I haven't tried Provider so rating 2* as I can't "not" rate!)I used this tip: to install the Google CalDav in Lightning & it seems to be working fine in both directions. That said, Instructions, Help, config etc., in Lightning AND Google calendar are a total mess. It took me over an hour to find the above, which stipulates that it must be a https address, but other tips send you to the xml / ical / http addresses (all http). Maybe above link is for DavCal only? What's the difference between DavCal & iCal? ...&xml & html..?All I know is my calendar works across my 2 PCs, in TB and on the Google calendar site. Without Provider. (And if I used OldeCrow's 5-min rule I'd still be in 1980 ;-))
