I have two short wheelbase (SWB) recumbent bikes, a 2008 RANS V-Rex and a 2020 Bacchetta Giro A20. And share a 2010 RANS Screamer tandem with spouse/stoker.
Last year I rode the V-Rex 46 miles, the Giro 3516 miles and we rode the tandem 466 miles. Heading towards similar miles this year.
We mostly ride the tandem on tandem club rides and rides in preparation for those rides. Making sure we don't forget how to ride it.
The V-Rex is a great backup bike - I've ridden it about 17,000 miles and is there if I need.
