Right. A peak detect charger needs to have a relatively high charge rate in order to obtain a discernible peak. Peak charging at C/10 is not generally done because the voltage inflection is too small. Because relatively high rates (compared to C/10) are used, a missed peak can be a problem. Overcharging at C/10 is not a problem. Overcharging at C or C/2 or C/3 IS a problem.

The very fact that your charger has two detection methods should tell you something. If peak detect alone were completely reliable then the temperature sense would not be needed. If overcharging because of a missed peak were harmless then temperature sense would not be needed.
