OK, so why did you say in your review, "The central mechanic, the task system, combines the traditional “roll under a characteristic” of Classic Traveller with the universal tasks of later versions of Traveller, especially T4."
I don't think, and you just agreed, that CT cannot be described as having a "traditional roll under characteristic" just because roll under was one of the sometime options.
AD&D has some roll under type rolls too. 3d6 for an Attribute or under is used a few times. But, I don't think anyone would consider AD&D a traditional roll under game, and the same can be said for Classic Traveller.
From my point of view, that really colors your review in a negative light.
You mention that you refereed CT back in the 80's during high school. If that's your most recent involvement with Classic Traveller, that would make your comments even more suspect, in my opinion.
To be clear: I'm not questioning your review of T5--just the parts of it that compare the game to Classic Traveller.
CT can't accurately be said to have a task system at all. It has a ciollection of separate mechanics by diverse skills.
