Hi all! After 2 failed attempt on BW reversal I am need for some help :-) I've followed the recipe below except that I've been rinsing for longer than Im supposed to... considering this doesnt matter for E6 I've been assuming it doesnt matter for BW reversal either?

I have not developed a lot of black and white at all, but I have developed a lot of E6 with good results. In my first attempt I used to little potassium permanganate, resulting in a non reversed film. But the negatives themselves didnt look that bad, apart from some stripes... which I have never experienced developing E6. On my second attempt I used a lot more potassium permanganate, but the film wasnt reversed now either. Instead I got some very, very, very thin negatives... uneven and with stripes... what may be the cause of this? Ive mixed the chemicals and developed like this:

First developer: 100 ml Ilford PQ + 400 ml water.
Bleach: 485 ml water + 15 ml Sulfuric Acid 50 % + 1 g (from 0,2) potassium permanganate.
Clearing bath: 500 ml water + 5 g (from 2) sodium metabisulphite.
Second developer: 50 ml Ilford PQ + 450 ml water + 0,2 g stannous chloride.
Fix: 100 ml Ilford Rapid Fixer + 400 ml water.
Stab: 2,5 ml Ilfotol + 497,5 ml water.

Develop 2 HP5+ 24°C Jobo CPA2 75 rpm:
- First developer 10 min
- Water x2 30 sek (probably more)
- Bleach 8 min (not 3,5 min)
- Water x2 30 sek (probably more)
- Clearing bath 2 min
- Second dev 8 min
- Water 30 sek (probably more)
- Fix 4 min
- Water x7 2 min (probably more)
- Stab 1 min

Any tips to help me in the right direction?
