Comparing SP with Fixed Odds Betting

Starting Price (SP) Betting: 

This type of wagering involves accepting odds that are set when races start. These rates show what most gamblers believe about each runner's chances. Here's what you should know about it:

  • Flexibility: With SP betting, one gets flexibility since he or she does not need to stick to given odds before the commencement of racing but instead receives such rates based on the market situation during running.
  • Market Influence: SP considers your potential winnings in case there is any movement in those last minutes towards getting off time. This can make sense if they are reducing their allowances.
  • Uncertainty: There is an uncertainty involved here; either way you cannot tell whether S.P. would be less compared with earlier available prices adversely affecting your returns.

Fixed Odds Betting

With fixed odds betting, you lock in your price at the point when you place your wager. These do not change despite happenings within betting exchanges after that point has elapsed. Here is why fixed odds differ from others in this category:

  • Certainty: Before placing a bet, you already know how much you stand to win when things go well for you alone amongst others counting upon this fact.
  • Early Advantage: When you have good insight or information, you can place odds that are high at the beginning before the market adjusts downwards.
  • Missed Opportunities: However, after placing your bet, they may increase and the best rates remain elusive to you.

SP betting offers flexibility influenced by last-minute market moves but it may not be predictable. Fixed odds betting on the other hand provides certainty and an opportunity to secure good odds early but it could deny me better rates later on.

Both methods have their advantages and suit different betting styles and preferences. Knowing these differences helps one make better decisions when making his or her bets.
