Hi @ShaneDeHorney,

When all is said and done, I believe any grade scheme in Canvas calculates as a percentage.  The points-based grade schemes help translate assignments worth less than 100 points into these percentages in the background, but I don't believe they work for points over 100 because of the rounding issues that would come into play.  I generally advise faculty at my institution to just use the standard percentage-based schemes to avoid all of the confusion the points-based schemes can cause.

Hope this info helps, even if it may not be what you wanted to hear.
