I have been gambling for awhile now, I noticed gambling at the start of a season is more risky than gambling when the strong teams are surfacing. At the beginning of leagues like premier league, bundesliga, Seria A, ligue 1 and other strong leagues like that, I noticed weak teams are strong but on getting to the middle, the strong teams at the first five leads are more predictable about the matches they can win, though they can still lose but the chances of strong team losing is at the start of the season. So, I am prefering now to bet more during the middle to ending of a season rather than the start. How about you, which one do you prefer?
It doesn't matter whatsoever.
The uncertainties that you talk about are all mostly priced into the odds that you get, so that at the end of the day you are essentially getting around the same value on each of your bets.
This is unless you have some sort of model/insight that allows you to consistently beat the betting market at a particular phase of the season. But I highly doubt this is the case - so really, just bet whenever you want during the season. The expected outcome will be the same.
