Good post @kworrom
There seems to be a few common themes in these 1.01-1.05 favorites. Lots of women's sports. Lots of teams who have an economic advantage, a disproportionate amount of money to spend compared to others in their domestic league (for example Real Madrid and Barcelona playing in the Liga ACB). Lots of national competitions where I guess certain countries also have an economic advantage or cultural advantage in developing their program over others.
My bold statement is, that a 1,05 in lets say Handball is way more likely to win than a 1,05 in football. The more room for error there is, the better. In Football one mistake can be crucial, in Handball not so much - you concede a goal because of some mistake, but it doesn't have that much impact, because there is around 50-60 goals scored. Even more so in a sport like Volleyball. You can go on a mental walkabout for a long period of time, but you might still find yourself only down a set. It doesn't matter, if you lose the set 0-25, 10-25 or 23-25, it's still only 0-1 in sets, there is no extra point in beating the shit out of your opponent in one set.
In women sports there is just huge differences regarding fitness, professionalism, mental aspects and whatever. If you take a look at EPL, every player is super fit, they are well coached, take care of their diet etc. The players from the smaller teams are just simply not that talented like players from Liverpool, ManCity, Tottenham. Now in the Womens Premier League on top to not being as talented, the girls from the smaller teams additionally are not as fit, well coached etc. as the girls from the top teams, so the quality gap is much bigger.
In non-mainstream women sports the gaps get even more big and the lower you go, the worse it gets.
Also, it's interesting how odds for many of these events seem to be offered only by sportsbooks with seemingly bad reputations... it makes you wonder if they would even honor an underdog upset or call bad odds. Plus if you believe in the favorite-longshot bias idea (

Good read, though I have never been into horse racing. The process of setting the odds by starting with the favourites and well known participants and go on from there is the way to go of course. I was following and betting cycling for 15+ years until most of the value had gone due to only one (knowledgeable) bookmaker making their own odds and the rest just copying them. There is 160+ riders in any given cycling race, so could I tell the winning percentage of some scrub from a middle of the pack team ? No. Could I make rather good price predictions for the favourites ? Yes. Now from what I observed, in horse racing there is no such longshots as in cycling. In cycling you see riders priced 100+ all the time. If you have some good reason and/or information to play such longshot, it's not THAT important, if you get @400 or @450. There is a difference, if you get @5 or @6 for a favourite of course (talking longterm here).
In the end it all comes down to value. Depending on your betting style and your mindset, each person has decide for themself what suits him best. I am more of an underdog bettor with my normal bets, without playing too insane odds. A friend of mine thinks that even @10 is kind of low
But he has long droughts of losing bet after bet of course, which can wear you down mentally and this should be taken into consideration as well. In betting a lot of ways work, but in the end you can't win longterm without being able to spot valuable odds, be it 1,01 or 10,0.
