I had taken the 4 days pass I would have paid a total of 260 CHF>

Yes but that is for passes sold in Switzerland which are much higher than the exact same pass sold in the U.S. in $ - use that figure and you may have come out behind i would think

a 4-day Swiss Pass, which i presume you are talking about would have cost $222 p.p. in U.S. vs 260 CHF or about $280 when converted.

$222 = about 200 CHF and also would have given the option of say hopping a lake boat in Montreux or on Lake Thun - doing extra things

But with your exact travels and if that's all you planned on doing you apparently were better off by a few bucks. But i point out mainly the benefits of the pass to do things you had not planned upon - like boat rides which then would have made it more expensive not to have one.

point is a pass means you may do more as the 'how much is it to do that boat ride' Q will not enter in

But for folks who know meticulously what they are doing and are not traveling huge distances, etc. then sbb.ch has all the fares and you can see which is better - but compare the pass price to what it would cost you at home and not in Switzerland at inflated prices for the same pass IMO
