Barometric Pressure on Ascent Day

[ScottVoo]

I heard a few people mention that the barometric pressure was unusual on the day of the Ascent.  Is it true that this can have an impact on performance?  I ran slower than I wanted to, especially above tree line....imagine that.  Maybe I'm just looking for an excuse   Does anyone know the science behind this?  Times in general looked a fair amount slower than last year.  Of course, it was warmer than last year too.  Thanks for any info.

I was also slower than I thought I was going to be.  Mark Tatum, the 55-59 age group winner, posted this link on Strava that talks about the effects of barometric pressure and high temperature:

This article makes it sound like it could have made a very significant difference.
