>>1381211Interesting, although it's all about them trying to sell you a product.
But guess what, OP? Unless you put a brand-new chain on your bike every week or so, and put a brand-new cassette (or cog, for your FG/SS folks) and brand-new chainring(s) on your bike every couple months, you're wasting more power to friction than even the worst chain lube on that chart.
Also note that even if you're a Pro racer on the UCI tour, a 2-3 watts one way or the other makes no real-world difference. Here's a short list of things that will affect your power output even more than your chain lube:
>Having a less-than-perfect nights' sleep>Slight indigestion>Allergies and/or asthma flaring up>Less-than-perfect air quality on a particular day>Your overall life-stress level being higher than normal>Didn't eat enough/ate too much for breakfast>Your hydration level being less than perfect>Forgetting to correct the air pressure in your tires..and so on.
I really can't take that chart seriously.
