Completely forgiven for not bothering with it, you are right, can be easily overlooked and stuffed up, and often not worth the added headache. But as a starter, I recommend just looking at the Friday night games and utilise those games only to benefit from the loop.
For example, only VC someone on Friday night. And always consider making a Friday night playing rookie (fringe player) as the Emergency. This way it should be relatively easy to not stuff up in terms of assessing whether you put the non-playing player on ground or not.... It's only when you start considering looping later players it gets messy.
Hope it works out for you more often than not. This year I have certainly gained probably about 100 points so far considering this every week.
