I'm not sure. You're not the first person to report this in Ubuntu and I 
suspect the the boot progress file is not being saved correctly. 
Remember, when you test a theme, this overwrites the progress file and 
the next boot will not know what the progress is. So you will need to 
reboot twice before the progress is displayed correctly.

Do you have "/var/lib/plymouth/boot-duration". What is in it?

Thats right, you need to seed it. I was going to add a seed function, 
but then I would also needed to add a time function to make a seed. I'll 
fix this soon.

Random gives a number 0<=X<1 so it will never be 1, so you don't need 
the 6.9 instead of 7. Also, counting from zero rules!
