my gut feeling after 6 seasons is that, at a certain period of the season, the game is programmed to keep some "suspense" within the leagues. To take my example, I am currently at first position of my league after easily kicking the teams in the Top 4. So yesterday, the "engine" decided I'd be trolled by the 8th team (at home, only me watching, 10Q less for my opponent, etc...), bringing the top 4 teams to 4 points difference.
If I were the guy who easily panics and who thinks his life depends on this game, I'd spend money on tokens in order to buy scouts... which I am obviously NOT going to do.
Your experience might be different than mine, but it's been typical for me over the last 3 seasons.
