Unless you have Kelvin leads, your DVM reading is probably high.? What do you read with the leads shorted?
I always have problems with the probes making good contact on small surfaces, too.
But really, 1% is probably good enough

Hello to All,
I measured the resistance at DC with my DVM.
I like Gufo's nice response and his link to instructions to build my own 50 ohm load.? I looked at Amazon for other 50 ohm loads.
There I saw reviews from several folks commenting that the loads that they purchased there were also way off 50 ohms, so they returned them for refunds.? So maybe I am not exaggerating or going into down a rabbit hole.? In any case I now have some instructions to build my own 23cm capable 50 ohm loads.
Thanks to everyone who provided input to my concern.
