So just to be clear here, your priority isn't even really supporting the club, if you could only do so from home...your only priority is this record of yours?
If I got to a point where I was physically unfit to travel (which will largely happen to us all at some point) then I would watch on TV.
In this situation playing in neutral venues behind closed doors is no more than an unofficial training ground game. Over the years the club have held many of those behind closed doors without announcing them and so obviously I haven't been to those either nor did I watch them.
I wouldn't consider these games to be competitive or of any relevance.
