Not at odds at all, depending on your setup it could be right
You should be able to provide 60 lph (1.5x max usage) with no pumps at all, i doubt many can. This is the benchmark Im talking about. This is an aviation standard i think.
I did lots of testing too and found fuel flow sensor is a big restriction, non running elect pump too. Jabirus standard fitment of sensor and fuel filter upstream of electric pump seems a bit odd.
Standard setup saw just 20lph without elect pump running at the engine. I got this up to around 50lph eventually.
As mech pumps are hard to test, and inflight not many can see their performance, its possible to be running relying totally on electric pump and gravity. If it stops or fogotten there could be problems at sensitive times.
Just to prove a point to me, soon after i had the mech pump stop intermittently, gravity almost kept it all going until periods of higher flow.
