While OP has good intention of helping fellow gamblers, I think this will be a 50/50 situation.
There might be a chance that players who are interested in parlays will actively join the community and thus, will make an active community which the members can exchange opinions and suggestions aside from the main posts daily by OP to gather more information, knowledge, and perspective. However, of course, players will have to consider whether this will be worth the shot. Since like you said, ten years of experience doesn't constitute to a guaranteed right prediction and winning. Since the ways and strategies might be a little outdated or might not work for others the same way it worked for him.
But yeah, I still wish this will be a success, just never set an expectation too high though to avoid disappointment.
I believe following the tips of a person blindly isn't a very wise move at all, no matter how much experience they have, it is always better to do your due diligence before placing the bets just to double check your chances and just to have peace of mind that you've chosen the right side. There is no harm in spending a little bit of time if you are seriously doing it.
The tipsters are not always right, just like OP. I respect what he is doing and the experience that he has in the field, but I believe even he could be wrong as you said. So it is better for his followers to note his tips but then do their own research and analysis based on that before placing their bets.
Odd are there for a reason. OP did this with that in mind and he's not really saying anything, other than the fact that the odds are in disparity between these matches and these teams to give bettors a general better idea of who to bet on and who to not. It's for them to decide whether they'd take it up and bed on the advantage or pick the underdog, OP has no responsibility whatsoever over these people's bets. Besides, it's not like these people who do bet on games that OP stated here are following him
information is literally stated in between each matches, so potential bettors easily will have a general idea of how these games may go. Jesus Christ you just can't let people have nice things these days.
