I've been quite clear that I'm talking about cost, which you seem to call "actual cost" above. Others have introduced expectations and probabilities and so on and muddied the waters.I no longer have any idea whether you're talking about actual cost (actual historical claims minus premiums paid) or expected cost (based on a statistical calculation of propensity to claim), and it seems as though you're flipping between one definition and the other to suit your argument
The fact is that insurers aim to make a small profit out of many to offset the larger losses they make on a few - that's how insurance works. If they underestimate and make a larger profit, that's not going to be given back to the many as discounts next period because the scheme might make a loss - instead, it should be extracted from the company by the owners as fast as rules allow (in line with the law of maximising shareholder value), so if any loss is bigger than expected, they can let the company collapse with the minimum required expense.
