General Mach Discussion / How fast can you send G90 and get accurate feedback on the current XYZ position

Equipment: ESS ethernet smoothstepper
Option 1: I have a project where I need to send G90 commands to the CNC. The increments would be very small 0.019685". How many G90 commands can i send in a second and how accurate would be the position reported back to Mach3 in that time frame?
I may need to adjust Z after each G90 command is executed so I need the exact X position at the time its processed.
Option 2: I'm at X=0, I send a G90 X10 command and I'm running at 60IPM. Will mach accurately report X current position as it traverses the 10"? If it will how often will I get that information back while its traversing that 10"?
I'm writing a remote control app that will use a laser displacement sensor (distance sensor) to measure distance from the object in Z as the X axis moves. I need to know how often I can get accurate information back to match the current X and Y with the distance reported back by the sensor.
Is the X and Y position calculated in Mach or reported back from the controller?
Thanks.
