I bought my Vado 5 SL EQ because of one very important reason-My LBS had one in stock in my size. If the Vado 4 SL would have been available I probably would have bought it but we were up to our eyeballs in pandemic s**t so I got what I could find. No regrets as waiting to save some money was not a good choice for me.Screw it. When I'm out on my Vado 4SL I don't see this spreadsheet. Love everything about my bike and doubt the 5 would deliver any more dopamine/mile. Go bike.
