How does Initial Layer Speed differ from Initial Layer Print Speed?

[jimid29 0]

I've been trying to improve some prints with very small first layer details and while I definitely see excellent results by slowing down the first layer print speed, having two first layer throttles is confusing. If "Initial Layer Speed" is not the printing speed for the initial layer (which presumably is the "Inital Layer Print Speed" parameter), what speed does it control?

Mother and two daughters.

The mother is Initial Layer Speed. The daughters are Initial Layer Print Speed and Initial Layer Travel Speed.  The Initial Layer Print Speed is what you will get in the gcode file for speed during extrusions on Layer0.

 

This is from FieldOfView's (AHoeben's) page on the Cura replacement patterns:

{speed_layer_0}    Initial Layer Speed    The speed for the initial layer. A lower value is advised to improve adhesion to the build plate. Does not affect the build plate adhesion structures themselves, like brim and raft. {speed_print_layer_0}    Initial Layer Print Speed    The speed of printing for the initial layer. A lower value is advised to improve adhesion to the build plate.   "Initial Layer Print Speed" can be linked or be a different number than what is in the "Initial layer Speed" box.  Maybe "Initial Layer Speed" shouldn't have a settings box and be just a heading for the other two settings?  The number may be used somewhere else though.
