[rrd-users] Use of LAST within RRA

I am wondering about the proper use of LAST within an RRA.
When I create an RRD file, I use the following definitions...
rrdtool create filename.rrd \
--step '300' \
I admit, I simply used 'cut-n-paste' based off what I did for the
AVERAGE and MAX consolidation functions, but as I reflect on the LAST
consolidation function, I find my self asking...
1) Do I need to keep so many rows of LAST points? or could I get
away with only 1? I mean, there's only one "LAST" point, yes?
Could I use these lines instead?
2) Do I need 4 RRA's with LAST? Or do I really only need one?
If so, do I use the higher resolution RRA (ie. no consolidation)
or the lower resolution RRA (ie. consolidate on a 1 day average)?
