When working in the clinic, there is commonly more than one RBT working with a client in a day. If, let's say, the morning RBT only runs 3 trials of a program, that data won't carry over onto the afternoon RBT's session. The data is essentially lost, as it is not graphed if less than 5 trials are run. Allowing the data to transfer to the next session if less than 5 trials were run would allow the data to not be lost, and allow the next RBT to continue taking data on that program.
