Funny installation time estimates

Description of Problem:
While installing beta for a new 7.2 distro on Alpha anaconda initially
told me that an estimated time to install "everything" was in an order
of 10 minutes. From that moment the estimate was constantly corrected
upwards to stabilize around 35 minutes mark, which was about right, but
only when around 60% of all packages was installed.
With version 7.1 was this big initial overshot but it was rather quickly
going down to a some reasonable estimate in 30-35 minutes range. It appears
that this was a better way to do that.
It's a guestimate
That value is guessed on how fast it was able to handle a package
so a small package like MAKEDEV though fast to physically xfer over, consumes a
lot of additional time running through it's pre/post install scripts. Big
packages like kernel-source skew the result because they xfer over quickly and
don't execupt any pre/post scripts.
