Why not restructure DRI points to line up with "ours?"
IMO. they should be the ones having to learn new math.
Now, I need to add more formulas to my spreadsheets.
May be multiplying HGVC points by 1.6 give an integer number of points most of the time where dividing DRI points by 1.6 will give a fractional number of points very often.
Example: a 1 bdrm scenic view at Ka'anapali Beach Club at 6,500 pts would be 6,500 / 1.6 = 4,062.5 pts.
They could round the 4,062.5 pts to 4,063 pts or truncate it to 4,062 pts but the number of points in any trusts must match with what they sold.
If somebody own 13,000 pts and HGV adjust it to 13,000 / 1.6 = 8125 pts and they round the 4,062.5 pts to 4,063 pts then this member will not be able to book anymore 2 weeks at KBC like he was able to do. If HGV truncate it to 4,062 pts then this member will have a 1 pts remaining after booking 2 weeks. So, the trust will be short in points.
The only solution to not screw trusts or members would be to keep those fraction of points but IMHO, it doesn't make sense to have fraction of points.
So, increasing HGVC number of points is probably a better solution than decreasing DRI points.
