Although the theoretical value might be 110pf the actual value of any one mica would vary because manufacturing techniques weren't as precise as the theory. The same with other components such as resistors and coils. So maybe the specific circuit of a specific radio ended up requiring 114pf. The assembler would find one that worked the best. Maybe the next radio would need a 108pf. They were customized for the radio.
