I'm probably too late and not even sure I'll be much use but I'll have a go...
I looked up pepper sauce on the WW site, and on a few websites for general pepper sauces and their nutritional information. The highest points value I came up with for a creamy pepper sauce was 2 points for 100g. So I wouldn't think you'd need to point higher than that. Mind you, if it was me, I'd probably point 3 points for 100g just to be totally sure. Sorry I couldn't be of more use x
i found tesco's actually do there own brand now and it had loads less calories than the colmans, etc. so i hope i worked it out right, for a 1/4 pk made with The One Milk it came in at almost 1 point
