Yes it is only kind of approximation and balancing "optimal step" 
between "less reallocation" and "more memory"
Which is application dependant, but may be that there are less 
applications, which will handle billions items in TFPList and which will 
need expand by 25% to save rellocations.
IMO it is reasonable for large number of items decrease "step" as saving 
memory will give higher gain for most applications.

In my case it will not happen ;-)), size is stable and will not change
