Not knowing your exact location for music, computers and your preferences for working on a big monitor and keyboard vs laptop with small screen/keyboard. Consider where I started out and where I ended up. I know you are more than tech savvy and get this. Just telling you how I evolved and it is WAY better. You don't even need to now carve out time for measurements. You can just fit them in to free moments you have throughout the day.
Started out with:
High powered laptop on my lap in listening room
USB for mic into same laptop
Mini jack sound out of headphone from same laptop to stereo RCA ends to Preamp
Power cord to laptop because you get carried away and lost in what you are doing and laptop runs out of power
That is a lot of cords in your laptop sitting on your lap and you squirm in your chair a bit and either the USB or the Headphone out becomes disconnected. REW does not like it when the mic is removed. You are flipping back on a small laptop screen between Xilica and REW. Xilica does not do tiled windows all that well. Small screen, hunched over in listen chair is not conducive to typing. You are listening to 20-20,000 sweeps over and over. Eventually I said enough is enough.
Ended up with:
Old laptop you probably have sitting around unused
Install REW software only, not xilica
Tuck it away in same location your equipment is with mini jack and USB always connected to preamp
Ethernet cable to this laptop
Ethernet cable to Xilica
permanent power cord to laptop as the batter is probably shot
Install Xilica software on your "good" laptop/computer with dual 24" monitors, full keyboard, mouse, desk, appropriate work chair etc. (mine work location is on a totally different floor)
RDP from work station to crappy laptop in listening area.
Run REW from the RDP session
Do all your Xilica tweaking on your work station
Now you sit in a good work area (with good posture) controlling the entire mic/REW rig remotely. You are not listening to high pitched sweeps for hours on end - Huge bonus your ears will thank you. You never move around and pull one of the many (mic/sound out/power) cables out or screw up the mic position. When you get around to the EQ wizard you will see that the low powered laptop may take actually minutes to optimize. If you have a wiz-bang-super-computer they take seconds. Jut pull the REW file via RDP to desktop of super computer and double click to open REW on your "real" computer. Now run your EQ optimization on the fast computer and transfer those settings to Xilica PEQs. Because you have real keyboard and mouse it is way easier because of dual monitors. One for REW and one for Xilica full screen. Your super computer will find actual Xilica box on the network. No need to be connected directly to it as long as Xilica, old laptop and good computer are all on the same network. I'm pretty sure you have to give Xilica a fixed IP, but it has been a while since I set it up, maybe not just need to know it so the Xilica Xconsole can be configured to find it.
