Can someone clear something up for me please as Harrison's website has me a little confused

Ok so I always thought 3.5lb tc meant 3 1/2 which is 3lb 8oz. Now I see the aviator is 3.6tc but I know the .6 stands for 6ounces.

So does that mean 3.5lb stands for 3lb 5oz or is it just Harrison confusing things on the aviator?

3.5 is 3 and 1 one half pounds or 3 pounds 8 ounces,3.6 is 3 pounds 6 ounces, I hope that makes sense .

There's different models

12ft Aviator flex 3lb 2oz
12ft Aviator plus 3lb 6oz

12'6 Aviator plus and 13ft Aviator TE - 3 1/2lb (3lb 8oz)

I guess its because calling the 12 ft rods 3 1/8lb and 3 3/8lb would look a bit weird!
