since ver 1.10 mit has always been 30knots at 14k westerly wind,
in ver 1.09 there were 4 wind layers all 30 knots and at:sw 8k, nw 14k,ne 18k, se 22k, (or something like that)
it meant once you got upto 8k you could do a spiral climb and always fly into the wind and made getting alt over a base quicker for buff interception.
