I don't think so. For instance, March 14th 2017 shows that KMD was around 30k sats. Not the 750 sats that you stated (I don't think KMD was ever close to being this low). Also, what makes you say that June 21st 2017 was during an irrational market? Is the market not irrational today? Are the dates that you specifically picked not irrational? Just wondering.
See above for the 1st part of how you're wrong.
As for the rest, between May 15 and June 15 2017, nearly every market irrationally "exploded" to new ATH levels. The majority of the markets today are still overvalued and the dates that I picked represent a realistic trendline that ignores both irrational and hype spikes that don't matter to any long term value.
