Hi,
Your link does not work for me. Apparently you modified it manually. Usually you can´t get wrong and just press the LINK button ...
in more detail for decativated boost converters:
for usual boost converters (non sync) there is a voltage drop (according load current)
* in all wiring / traces
* evental series resistors / current measurement shunts
* the catch diode
where the catch diode will dominate, so expect 0.3V ... 1V of voltage drop.
An activated controller will compensate this drop.
for sync boost controllers, the diode may be overruled by the rectifier MOSFET, thus the expectable voltage drop may be way less than the usual voltage drop. It will depend on the IC whether the rectifier MOSFET will be activated or not.
