It will be really a difficult task to gather that information to add them in the table. You aren't going to get the actual data from the support agent in most of the sportsbook about this. Therefore, you have to do a lot of calculations to confirm the house edge of the sports betting in each casino. Glad to see that you are trying to update the your thread with the latest data and better details. You may add the house edge column too if you can manage the time to do it.
The odds boost is a promotional feature of the bookies. You may ignore this part during the calculation of the house edge if you wish.
So, the idea was that I pick 3-4 popular sports that are very popular and one that's niche(pre match bets). Like NBA, Soccer, Tennis and eSports. Then check the average house edge for all the sports, usually, the house edge shouldn't change much from sport to sport. Post the outcome on respective sportsbooks. To make it fair, it will be the same event across all sportsbooks. I know that some sportsbooks give better odds for a specific league or sport, hence using multiple sports to make it as fair as possible. A ton of work indeed. Depends on people's interests. Will it make someone switch sportsbooks? probably not, unless it's groundbreakingly worse odds a sportsbook is providing.
