Meaning of differing victory numbers on www.airaces.narod.ru website
 

Hello. I'm wondering if anyone can tell me what the differing sets of victory numbers on the above website mean.

For example, in the case of Alexei Vasilyevich Alelyukhin, at the foot of the table detailing victories, there is 34+6 [27+1]
In the case of Nikolai M Skomorokhov, the numbers are 46+8 [43+3]

Thanks
Peter
