If a punter is securing value odds for his/her selections, then backing them in multiple bets is a good way of boosting profits, providing they win, or are at least are placed in the case of Each Way
However, backing overbet selections in multiples is one of the quickest routes to the poorhouse.
Must admit the I am finding it frustrating with the Lucky 15
experiment that I am running at present
as losing runs can be tough on the nerves, plus it is almost impossible to secure the best value odds on each selection when having to place all bets with just one bookmaker and the profitability of the experiment is likely to hinge on securing a few trebles, or fingers crossed an all correct bet (less than 10% chance) over the 100 day duration of the experiment.
