About PMF Options

Hello guys

Currently my OpenWRT's WPA2 setting runs with following conditions

PMFMFPC(MFPC) = 1
PMFMFPR(MFPR) = 1

If i am understanding correctly, MFPC's 'C' stands for Capable(Optional), MFPR's 'R' Stands for Required.
'Capable' here means, doesn't matter that devices Supports PMF or not to connect, and 'Required' means that devices MUST support to connect.
i searched that there are 3 conditions for this, and MFPC is on, SSID supports PMF but lets device wants to connect to decide either to use PMF or Not. I'm not sure what this means exactly that

" the device should support PMF but the device can choose either to use or not to use PMF "
or
" doesn't matter device supports or does not supports "

If my PMF Options are like this,

# 1st case
PMFMFPC(MFPC) = 0
PMFMFPR(MFPR) = 0
# 2nd case
PMFMFPC(MFPC) = 1
PMFMFPR(MFPR) = 0
# 3rd case
PMFMFPC(MFPC) = 0 (or 1, Since MFPR option is 1, so i think this really doesn't matter)
PMFMFPR(MFPR) = 1

and the device which does not supports PMF, wants to connect with each cases
1st and 2nd cases will connect without any problems, and for 3rd case, cannot connect.

Am i right?
I would like to test this, but all my devices are supporting PMF, so i cannot test it.
