6x5 minute steady state

I used Riverside Drive from Delta to about the barge terminal near the railroad overpass for each of these. I'm ahead of schedule this week but I assumed we wanted two days in a row on the intervals so I did the 6x5 steady state today. Using my tt bike, I held 342( west bound; aero; 26.6 mph) , 349 (east bound; non aero; 22.88 mph) , 342 (West; aero; 26.7), 350 (east; non aero; 22.66), 338(west; aero; 27.24 mph), 334 (east; aero; 24.25). I was curious to see power and speed given aero and non aero position on the bike. I can generate a little more in the non aero but speed is certainly faster in aero. The elevation gain/loss is similar when comparing east and west bound on this road. I have been working with my saddle height also.
