Maybe I used the wrong word, 'resonance', but I was referring to the
lowest SWR match, which I would assume for the example to be less than
1.5:1 on a given frequency.

'Resonance' means where the reactance is zero.
'Lowest SWR' usually means SWR read on a meter calibrated
for 50 ohms. These two conditions may be quite different.
40+j10 is not resonant but has a 50 ohm SWR of 1.4:1.
10+j0 is resonant but has a 50 ohm SWR of 5:1.
