I read somewhere (here ??) that when a new index block is created, it's filled initially with only 50 % of the space possible. At that time of reading I interpreted the argument as stupid, for a thing we call a bug indeed. However, looking at all the manipulation VFP has to do in order to insert a new key somewhere, there can be much truth in the argument "speed". IOW, instead of shifting ranges of keys to next blocks, now it can shift within the block, until it is full. May be very much faster indeed.
But all is just my guess of how things are working internally.
