Wave sequence question

We have a number of .LIB files with a number of data points (i.e. 3334 points in each of the 10 .LIB-files) that we want to run in a sequence. These data points are supposed to simulate grey scale transitions (total 20 transitions between 5 grey scale levels) for a LCD display. The data points are taken from a real display and we want these data points to control a LED light source. We want the LED to simulate the original display response that runs at 60Hz. The original data were sampled at 5000Hz.
The setup-up looks like this:
Function Freq Offset Voltage Time Filename
4 1 0.96456692 2 0.6668 testeizoB1.lib
4 1 0.96456692 2 0.6668 testeizoB2.lib
4 1 0.96456692 2 0.6668 testeizoB3.lib
4 1 0.96456692 2 0.6668 testeizoB4.lib
4 1 0.96456692 2 0.6668 testeizoB5.lib
4 1 0.96456692 2 0.6668 testeizoB6.lib
4 1 0.96456692 2 0.6668 testeizoB7.lib
4 1 0.96456692 2 0.6668 testeizoB8.lib
4 1 0.96456692 2 0.6668 testeizoB9.lib
4 1 0.96456692 2 0.6668 testeizoB10.lib

However, we are very uncertain about the Freq (1) and Time (0.6668) settings. What should they be? Each .LIB file shall be used only one time and each sample point shall come out at an interval of 0.2 ms. The transition between each .LIB file shall be smooth

According to my tests it seems that 0.6668 seconds is too short time for the PCGU1000 to load and output new file data.
One solution may be to try to combine all the ten files as a single file and run it in the LIB mode.
