Hello Shay, thank you very much! The content on your site is excellent; I have read the Course 101 and already feel much more confident on my CSS skills (and especially the really confusing things like floats and positioning).
The most immediate difference is that Lead Honestly communicates and works directly with a manager, and by extension their employees, where 15Five works with all parties. As a result Lead Honestly is able to be applied however a manager wishes, and is offered at a much lower price point.
@lucisferre, you're 100% correct here. I certainly don't ignore 300-600ms differences but I only look for them after I've exhausted other, perhaps larger, gains.
As for how many times the test was run, it was randomized but but somewhere between ~60-100 times.
I'm not really seeing why I would want the label of the section in question hidden when I'm dealing with it, and at least for me there's not really a parity between 'dealing with' and 'hovering over with my cursor' anyway, unless I'm copying the text. The bright orange color and the constant flashing on/off just adds visual noise and makes it difficult to really read the labels anyway, imo.
Making the guide responsive is an absolute must, and something I am looking to do right away. For now I just wanted to get it out there and start collecting feedback.
