Being new to 'soft washing ' I'm trying to figure out a formula for mixing 12% hypo. Is this accurate?   Formula in 25 litre mixture.               

12%.  ---  Hypo/litres ----Water/litres   5%.    ---    7.5         -------   17.5.           4%.    ----   6.25.      -------    18.75.        3%.   -----  5.            -------    20.              2%.   -----  4.            -------    21.              1%.  -----  2.            -------     23.                                                                             For example.  4%= 3:1 ratio.               Hypo= ( 25×1) / (3+1)= 6.25 litres.   Water= (25×3) / (3+1)= 18.75 litres
