In our study (CBC, we use SSI v7) I would probably have to use conditional pricing solution. There are 3 products A,B,C . Products A and B are similar , product C differs a bit technically but competes directly with A&B and is priced higher. Below is example of price levels for them :
Price AB ($10, 20,30,40,50,60) Price C ($50,60,70,80,90, $100) as you can see levels with prices $50 and 60 overlap. Exp. level 6 for price AB ($60) equals level 2 for product C. I know I could compress to 6 levels price ranges $10 to $100 and interpolate but jumps between prices (d=20) and implemented prohibitions would decrease sensitivity - so this option is not taken into account. So my question is - whether by ovelapping price levels for product AB and C I don't harm the study by doing something against the rules ?
I would be grateful for any remarks,
