I see this constantly in this experiment matches go wrong at the lowest odds, and to be hoenst I would have placed bets far easier on greater odds, For example on Bayern and Barcelona despite being 1.8, no way I would have actually taken a gamble on Atalanta at 1.4 or bet on Arsenal, no, not even thinking of!
All opportunities are always good in the favorite team but it would be much riskier to take all the top teams from each league and make it multi bet, it would be better to take it in one particular League and all slip are taken from several team in one League which is clear never exceed the limit like betting with 5 to 10 team at once.
Every gambler must have experienced condition like that where taking favorite team that has an advantage on paper but at one time the team experienced failure and embarrassing defeat, that why I always say about not focusing too much on the superior team because in football anything can happen even though it is an unreasonable result.
Surely at most times it can seem very hard to determine a winning team between that of the favorite and the opponent, sometimes most of the players in our most preferred team may not be physically fit enough to bring out their best performance which can be unknowingly to us the gambler, those players are humans like us such their body might to have enough rest but due to duty calls, they will be out and might not be on their best performance that is fatigue hence, that is one among the reasons why sometimes a team you consider to be weaker team wins the the favorite team.
