[Supers][Spaceships] I/C/D/M Scale and points

[TJA]

Hello,
on GURPS Supers, p18-19 there is a description of "classes" of Supers, their point-totals and scales of combat abilties.

The "biggest" supers class, for example, named "M" from Millenium allows for the following abilities:

Max. dice of Innate Attack or basic swing damage: 15000d
Maximum DR: 50000
Maximum Damage Reduction factor: 10000
Maximum Levels of ST with Super Effort: +28 (+100000)

Such a Super could have up to 3*500d of dDam as used in GURPS Spaceships and is therefor comparable to a Spinal Battery with an Output of 300TJ (see table on Spaceships, p67) and damage type "dDam1".

Quite impressive ... and i like this vision!

But the rules on Supers, p18-19 seem to limit Supers to 6400 points!

With this "little" amount of points, you just cannot reach the above limits on damage dice and DR!
And this, while IT:DR and S-E *are* within the reach of that point-limit:

IT:DR 10000, 600 points
Super Effort +28: 750 points

Is this on purpose?

For 600 points, i can just get 600/5 = DR 120 or between 120 and 360 dice of damage!

I just cannot see how that is constructed in a logical way - despite the fact, that with 6400 points only DR 1280 or between 1280 and 3840 dice of damage can be bought.

Something is wrong - for me, it seems the 6400 points need to be adjusted OR (and i like that better) the cost for damage and DR need to be scaled down like the cost for IT:DR and S-E (both of which do not follow a linear progression as the former two).

What do you think?

How would you handle this situation?

o Limit a player to 6400 points and therefor much "too low" damage or Damage Resistance?
o Increase the point total?
o Change the cost progression?

Thanx for your thoughts ...
