If you're in hurry with the result, you have the option to place a bigger amount on a single bet but know that the risk of doing this is very high and most of the gamblers here want's to play longer, that why they are placing a small bets even on a single game as long as they get entertained. Well, the tips in OP is very helpful if we are going to understand it. I like the last part on recoding your bets because this can help you decide either to continue placing a bet or just stop and be back the next day. Sports betting is not easy at all, we have to analyze and know what works for you, we should always look for the odds as well.
I think that increasing our bet size doesn't speed up the process but if this was done in some casino games like dice then yes. Also I think that what @kakmakr was doing there actually saves more time than manually betting one by one. It is perfect if you are in a hurry like you will go outside or do something else.
Big or small bets, single or multi games, all of them can still go a long way because the outcome in sports betting usually takes time. Very different from the casino games where they are fast paced but if all what you want is entertainment then you better play in casinos but if it's for the profit then you are already on the right place.
