Yesterday I hated my smart phone apps. They wouldn't lie to me and swear I was faster on my road bike than on my upright hybrid, at least on a long downhill run.
Of course the upright hybrid has the advantage on that particular run, especially on days with the wind out of the south. It's heavier, and sitting upright catches the wind.
But, dang it, I thought for sure a 23 lb road bike would be significantly faster than a 30 lb hybrid. What good are these newfangled apps if they don't lie to me?
