thing just plug t one instead of zero in the same expression and get the same result for the lonzeva algorithm that has an interesting point that actually the line that corresponds to this uh to this threshold it's set to it it reaches the line lambda two equal one at uh sorry delta tweak one at delta p equal to so there is a three critical point so if delta p is bigger than two there is no loss of a hard phase anymore but maybe let's go back to this popular explanation what was wrong with that you know absence or
