Pipetting to the side of 96 well plate or directly into bottom with liquid?(&lt;5ul volumes) Hi just joined a new lab and have had to relearn new protocols for working with microRNA qPCRs

The person who demonstrated the protocol pipetted to the side of the wells to avoid bubbles but it goes against everything i learned before where master mix was loaded and samples, then primers pipetted directly into the bottom of the 96 well plate

I've gotten terrible results with pipetting to the side of the well and am just confused over the whole thing, 

what are the pro and cons of either method? 

If there something specific with the qPCR reader we are using the applied biosystems quantstudio 7 flex
