HD, I mean all other things being equal, one runway operating in SRO will have more movements than one segregated mode runway, albeit if the fates (and SID splits etc) align you could approach SRO movement rates with a departure only runway.
SRO runway, mid 50s?
Usual departure only runway, mid to high 40s?
Arrival only runway, low 40s?
I'm not comparing SRO with a two-runway airport operating in segregated mode.
I say by definition because with SRO you effectively negate vortex.
