Basketball advance rates

Good afternoon. I would like to tell you a little about my activities and ask for advice from experienced players. What I do is place bets on events that have taken place. For example: let’s take a basketball match, I have sources that are 10-12 seconds ahead of the quotes. With a three-point shot, the coefficient for an individual total can change from 1.9 to 1.4 or 1.45. There is also an overall total in the quarters of the points race. That is, I’m betting on a coefficient of 1.9, but in fact it’s 1.4. How would you use your bankroll with this strategy? At what point would you bet in the middle or end of the quarter. We would bet on the favorite or the underdog. I’m looking for the best approach to this strategy. I would be grateful for feedback.
