Why do people always insist on posting sub-second performance benchmarks in blogs? Is it really so hard to put a for(var i = 0;i < 1000;i++) {} around the code?

Why do people always insist on posting sub-second performance benchmarks in blogs? Is it really so hard to put a for(var i = 0;i < 1000;i++) {} around the code? I'm not talking about making the benchmarks actually being reliable, but make them at least pass the most basic of inspections. Your computer could be doing anything in the few seconds that your application ran. Is your blog really that worthless to you that you couldn't wait 5 minutes to establish that what you're saying holds water? edit: okey, I need to sleep a bit better, I'm coming off bitter again :P
