The bonuses for most of the attributes and the skills are set based on whole number advancements but you rarely end up with a skill or attribute as a whole number because of the fractional advancement system. What happens is you wind up some small faction either over or short on most if not all of your skills or attributes once you hit the cap. What happens to these fractional values? Are the lost skill and attribute points or are they being calculated and providing some benefit?
If they are being rounded out(ie:lost), I would suggest the developers find a way to round them to a whole number for the attributes and, at least, round them incrementally (30, 60,90,100) for the skills.
