I agree with the nose heavy tapering (I found this easier to control and to crack)

PS: I do my calculation using the weight and not the number of strands...

because I want tapering on the mass (weight)

So, in adimensional numbers a single strand going straight the tongue equal to 1 (eg: the core with no BBs or ballchain); a strand plaited equal to 1,5 (sqrt(2)=1,41 because ideally we are plaiting at 45° and that's the value of the hypotenuse of a right triangle with cathetus equal to 1).

And a number of 1,2 if twisted strand.

PS: this the weight of my material:

each 4,5 steel BB = 0,37 gr (22 BBs in 10 cm of tongue =8,14 gr)

(I wish I could find L size ballchain... in the range of 6 gr each 10 cm)

each M size ballchain = 0,17 gr (29 BBs in 10 cm of tongue =4,93 gr)

each S size ballchain = 0,11 gr (33 BBs in 10 cm of tongue =3,63 gr)

(I wish I could find XS size ballchain... in the range of 2 gr each 10 cm)

10 cm of ungutted paracord = 0,70 gr (multiplied by 1 if used on the core)

10 cm of gutted paracord = 0,23 gr (multiplied by 1,5 if plaited; 1,2 il twisted; 1 if used on the core or dropped straight parallel to the core)

Ah, I'm not considering the weight of the binding... simply I did'n yet... (but I feel that somehow with a good tapering on the binding itself it it will not affect the result of tapering)

Those are example (don't look at the value on the y axis... in the first photo is gr/10cm... the second has only adimensional numbers), on the x axis there is the tongue (from left=handle -to- right=fall knot):

PS: "Lineare (Massa)" is the trend line (tapering) of "Massa" (the italian translation of Mass)... so if Massa is close to the trend line I achieved the goal I'm looking for.
