The point of my comment was that it was not always possible for some to receive more than the training they did receive, chiefly because there was not enough time. It was hardly the ideal but other things also matter. One will never be totally prepared and one will never be at the peak of perfection. That does not mean, however, than you can't be "in good training," physical limitations notwithstanding.
Some training programs are based on the requirement to train people quickly, others more to take advantage of fewer limitations of time and expense. But there are always some limits.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
