well, hccapx files as you can see here https://hashcat.net/wiki/doku.php?id=hccapx can consist of several networks/handshakes etc. if you crack several networks at the same time with -m 2500 = WPA/WPA2 with multiple ESSID/networks ("salts"), the estimated time will of course multiply by the number of different "hashes" (or more correctly: salts/networks/essids).
Therefore I would suggest to analyze the hccapx file and also look at the status display (hitting "s" in hashcat): it should say Recovered x/y and salts z/k where these values indicate how many "hashes" and different "networks" are being cracked at the same time.
