You're probably right PP. I was just bitter after hearing it happen again yesterday (turns out in spite of words like "stone motherless" from the caller it actually finished nearer half way). A month or two ago two days in a row very short priced favorites finished last, the first had heart palpitations and arhythmia or something according to the stewards report. The second one only had a much increased heart rate. I cynically thought to myself "Ah good, they've got the dose right at last".
It was just a (probably) unjustified swipe based on no more than sh*t in the liver. :-)
