double values in axis tables

This sort of relates to Kinds thread about rescaling the axis table.
In some of these tables, Ford uses the same axis value twice with a different produced value in the table for each.
Anyone have any Ideas why?
I asked H&S TECH a question Regarding the 0-1020 axis values in the transmission tables a few years ago, & this was their response"
" The 0-1020 values represent 0-100 percent throttle. They are not scaled correctly because the TCM uses floating point data representation for those values. We cannot currently manipulate floating point values with our MCC software, so they are seen exactly as the TCM sees them"
I still don't understand what "Floating Point Representation" is, but I wonder if this has something to do with using the numbers twice?

For the trans I have changed them without any issue. I also changed the injection duration y-axis without an issue. I've pretty much changes mostly the axis in the tables I use. I have found it has allowed me better flexibility and control, very similar to why Dustin and Mike rescaled the low boost fuel tables.
