cloning of PCR products - errors?

Hello Richard,

 I always thought that this was just to keep fidelity higher & would 
have expected LOWER product yield with 1/4th concentration, albeit I 
observed myself one day same product yield with half amount (was Tfl 
PCR, other concentrations were not modified)...

 Hmmm, the Km of HiFi-thermopols is different & often more (free?) Mg++ 
is recommended, but [dNTP] is higher too...
