Ok not within a week but within three months of each other
Bottom line is just because I said there were 4 it doesn't make it true or not. If it's 3 or 5 I don't particularly care.
You conveniently choose to ignore the massive exaggeration of timeframe which you previously employed... that's a pretty big deal as you specified a rate of failure of four in one week. If that wasn't due to bad luck then that would have been 48 failures in three months. Yet in fact it was only three/four/five failures or shut-downs over a three month period - a massive difference! Get your facts right before posting such absurdities
