It would be much much higher than that,
and 4 are dead...
That is about 0.00002% failure rate, It is very normal
Mine has at least 10-20 dead, I don't care....
They didnt say anywhere in the literature there are 21MPs a certain number of which will be dead. I do care. Its a surprise and not one I enjoy
The bottom line is that its a complete pain to clone out
