I partly agree with you, but not completely. The project only had about 200 
days to go maximum, until we reached keyspace exhaustion. They had to know 
the chance for finding the correct key was quite big in the last 6 months. If 
they started working on a new client around then, and not open the RC5-72 
project before RC5-64 was closed, it would've been ready when RC5-64 
finished. They could even make all the clients have the RC5-72 cores already, 
but not open the projects in the keymaster. If RC5-64 finished, they simply 
could've closed it, and opened RC5-72, ant with the vast majority already 
updated to the new cores, most computers would automatically start working on 
it. This all ofcourse requires that Dnet staff has the time to do this, which 
i know they don't, so i understand why they didn't follow a scenario like 
this. I just hope that they consider it when next time we run into the same
