It's a huge number. I am surprised they have the manpower.

In fairness gp says less than 1%.

I would expect 'less than 1%' to be 0.1% to 0.99%. 0.1% is still a high figure.

I would bet it’s closer to 0.99% otherwise wouldn’t they have phrased it something like “slightly more than 0.1%” to make it sound smaller?

If I was talking to a reporter and the real number was .01% I would still say "less than 1%" to make sure I was properly understood. The whole reason we use percentages and say "one percent" instead of "point zero one" is that some people tend to get confused with decimals but not with integers.

EDIT: And part of this is just how we say things. "Twenty" is just easier to parse in a conversation than "Two Oh" even though the later is perfectly comprehensible when written out.

1% vs .01% would be overstating the truth by 100x. If you were a spokesperson for apple you would want to make that number seem as small as possible.

"One in ten thousand" is clear enough for everyone though.
