Since I'm not gambling for fun, I don't let my instincts have greater part of me while gambling but I don't ignore it either. Some times I have followed my instincts and they didn't fail me so I don't ignore them completely but make sure to combine their tell with my logic as I reason on my choices.
That's good if your instincts didn't failed you because many gamblers won't trust their intuitions anymore because for how many times they have failed. I'd ignore my instincts at times because it's not that good at all to rely on it and that's the reason why I don't like being on it anymore. But just as you, there are times that I cannot ignore it and that could have been the reason as well why I was able to win some but that's not happen as a daily thing to me.
I feel the same way. I'm not really sure if instinct really helps me in making bets. The event can still be true, but there are still many failures.
So from here, I will realize that the sensitivity of each gambler in relying on their instincts in making bets is different. Some may be very accurate, but some are also wrong. I will trust data and statistics more than my instincts when making sports bets.
