Normalized power v average power

I’m doing the 6 Week Sweet Spot plan. The plan asks for normalized power, but I basically have been using lap average power for intervals and such. Am I doing it wrong? Thanks.

No, not necessarily. For steady sweet spot work average and normalized power will be pretty close to each other. On undulating terrain they may differ. Ultimately when performing sweet spot work both your average and normalized power falls within your sweet spot zones.
