Should have asked this a long time ago. Why are there gaps in the EN Power Zones in final surge?

Power Zone Name. Low-High. FTP: 250 watts

Zone 1 (60% - 70%). 145 watts-168 watts

Zone 2 (70% - 75%). 169 watts-182 watts

Zone 3 (80% - 85%). 194 watts-206 watts

Zone 4 (95% - 100%). 230 watts-242 watts

Zone 5 (110% - 120%). 266 watts-290 watts

It's like half my ride doesn't exist when I look at time in zone chart.

    So you get a little separation between zones for a definitive difference in "work".

    Like going from Z3 at 206 to Z4 at 207. Is one watt really a new zone? But going from 206 to 230 certainly is.

    Ya, it does goof up the "time in zones" metric as anything in the gaps doesn't count or get credited.

    I kind of think of it like what some plans call Zone X -- not easy enough to be easy training and not hard enough to be hard training. I think it's just to get us to really focus on where the work should occur. That being said, I kind of wish the "don't train here" zones had a name ;-)
