Still getting unit prices wrong

When, oh when are you going to get your unit price algorithm sorted out? Cheesy slices at £0.83 per 255g does NOT equate to £0.02 per 100g as you state. What youve done is divided the unit price by the number of slices, which is not relevant. You cant do part of the calculation on weight and then further modify by the number of items in the pack. You get a completely spurious result. £0.83 for 255g equals £0.325 per 100g. I have pointed similar errors out on at least two occasions in the past but you still do nothing about it. What is the point of a comparison site if you cant trust its calculations?
