Why do workouts feel easier on ERG?

m not doing anything different, aside from necessary gearing changes for intervals on resistance mode

I ask because my previous trainer was a Tacx Vortex that would read a bit high in the little ring but much higher in the big ring. I was crushing my FTP tests, but always in the big ring and spinning at 110 rpm. Was quite a comedown when I got my (current) trainer a CycleOps H2.
