Disruptive effect and control are always in balance to each other. Although everybody feels an ardent longing for 100 disruption together with 100 control this is not possible. As the control is very high with 95 a value of 80 is with respect to this very high.
I don't quite agree with that. Meteor 8512 is generally considered to be a high control rubber with great disruption, which probably just means that a lot of people are capable of playing effectively with it. Butterfly Feint Long III isn't thought to be very deceptive, but very effective in stopping/absorbing attacks as it turns incoming topspin in very heavy backspin, so it is very disruptive, and still has high control according to most. There are, in my opinion, also many LPs that in capable hands have great disruption but to the unaccustomed are difficult to use; in many cases this is mainly because they are relatively fast, and when used on slow blades or after extensive training, they are easy to control as well; other rubbers are high throw and need training time to get the angle of the blade right. Control is, I think, almost entirely a subjective value. Disruption also, I think, and at any rate there is more to it than simple reversal, or the potential of producing knuckle balls; most LPs are designed with a specific purpose in mind and if used for it well (that, at least, depends on the player, so is a subjective factor) are quite effective, hence quite disruptive. Anyway, it would be much more informing if manufacturers instead of giving just numerical values would explain what a rubber is intended to do, and how it does that. Something like: "Designed to absorb speed and reverse spin, the rather stiff pimples of this LP have low friction and are not very elastic, so the rubber is good for all sorts of blocking and counter-hitting or aggressive pushing close to the table, but will do less well for classic defence as it will not really add to incoming spin."
