Congrats on getting back down to 201. Small gains like that are nearly always temporary and only not temporary if you let it throw you off.
As for measurements, I think when you're at the other end of this journey you might wish you had taken them. They're just another metric to be proud of.
However, I don't recommend measuring every week, because of those very reasons you mentioned - it's difficult to find the exact spot every time, and often the week-to-week losses are small enough that they're difficult to read. A tip for finding the same spots month after month: Create your own reference sheet. Find markers on your body - freckles are particularly good for this
and things like elbows and belly buttons work too. Measure the distance from your marker to where you want to measure, then write down how you found that spot and you'll always know where to go.
So for me, I measure my waist (and have lost 4" there so far, I am happy to say). This is what I have written down: 1" above the belly button, standing tall, stomach comfortably sucked in. That way I know where to measure and I have a reminder of the condition my posture should be in to mimic each time. Same goes with R thigh, R upper arm, bust, and hips. I have something written down for each to refer to so I know where to measure. I do this once a month and I *love* seeing the progress!
Not that you asked for all that but thought I'd share
