One of the biggest problem with single sided powermeter, is that the imbalance can be (very) different at 150w and 300w. I am at 60-40 at lower intensities and almost 50-50 at Threshold+ and VO2Max. In my case, it would mean that if I take the Ramp Test result (last one minute x .75), I would probably “under” train while doing sweetspot, tempo, etc… but it could be the opposite if your imbalance appears at higher intensities instead… Not sure if it’s clear 
Regarding your setup, you also have the option on the Wahoo app to read the number of your Powermeter directly on the Kickr. It works wayyy better than the Powermatch! The Kickr will then just keep the power data of your Vector and deal with increase/decrease of intensities send by Trainerroad. Much better, trust me, especially with a single sided PM. Feel like Powermatch doesn’t deal that good with the more fluctuated data of this kind of PM!
