You were nowhere near highest load yesterday, the day before that you were sixth highest, 39th highest on the 28th, nowhere near the top on the 27th. It seems to fluctuate quite a bit depending on the day. Our log files don't always do a great job of indicating where on your account the load is coming from, but one script that is coming up is
/home1/biasaf/public_html/wp-content/themes/gozumu/random.php
and the timestamp on it is Feb 28th so maybe that might be the culprit? A common misconception is that no matter how you set up a wordpress blog it can't cause high load. I guess this might even be true for newer versions of wordpress with no modifications, themes, or plugins. I say newer versions because some older versions had a wp-cron.php bug that would cause massive load anyways. An analogy is like saying, "It's a Toyota Prius! How can it have bad MPG?" But then you see the whole picture, and someone has strapped rocket engines on their Prius that guzzle 1031 gallons of fuel per second.
