This method can also be called "raising the bar" analogous to the way high
jump and pole vaulting contests are carried out in track meets.

The "ante" is the bar level.  As the bar gets higher and higher, the
weaker candidates start to drop out.  Once a candidate misses, the
possibility for recovery still exists, but it is not likely.
