someone has the extra figures.
5 years ago in the 80's I think $82 per point. (might have been higher)
10 years ago in the low 60's. $62.75 per point.
compare prices to what you are spending now on a WDW vacation. Since you are renting points already it might not work for you. but do the figures anyway.
now some people compare it to an investment. but I have money I spend on vacation and money I invest - two different places for me.
however if you want too

take away $075 for a deluxe, $50 for moderate, and $25 for a value - recent discounts
taxes have increased to 12.5% for most WDW resorts, 13% for the all stars.
inflation - disney has increased their prices around 4.5 to 5.5% lately although have been know to increase 10% in one year. (one year they had two increases....) - so I would do this number at 6%
