Tetenal Colortec C-41 Stabilizer dilution

Hi guys, I don't understand the dilution rates on the manual, hopefully someone can shed some light on this.

For 1L: 900ml water + 100ml stabilizer
For 5L: 4950ml water + 50ml stabilizer

This looks odd, why do I need more stabilizer for lesser amount? Also, I only need a 1L working solution however, the concentrate seems to have 50ml only, I could find a 5L storage but that's gonna be such a pain...

That looks wacky to me too. I think, looking at this, that they either made a typo and it should say 10ml, or it makes no difference how you mix it.
My unicolor kit says 5grams of powdered hexamine to 1L. Not sure what chemical Tetanal uses. This post is probably not very helpful, sorry.

There has been typos in the past.

When in doubt, check online
The correct amount should be 500ml...it seems

From the Instructions for TETENAL RAPID NEGATIVE KIT :

"* “STAB” formulas for 1 litre and 5 litres are different !"

100ml for 1 litre and 50ml for 5 litre is correct.

Manual should be checked. It is different for all packaging.
I have now the 2.5l kit and that stabilizer is something like 1:4 dilution.

Yup, I misread the manual last time I mixed it, and now with my 5 liter kit which I mix bit by bit I have a VERY LARGE JUG of stab. No big deal, the stuff lasts longer than the development chemistry anyway.
