[Programming Help] - Accuracy in backtesting when increasing replay speed

Hi, First of all, I think Sierra Chart is an amazing trading platform. One area where I think it could be improved, however, is broader parameter testing for automated strategies. I have a question for the Sierra Chart technical team. Does increasing the Speed setting to very high values, such as 400 or even 1000, affect the accuracy of a backtest? In other words, if I run the exact same strategy with a Speed of 1 and then with a Speed of 1000, should I expect the results to be identical, or can higher speed settings reduce the accuracy of the simulation? Thanks in advance for any clarification!
