Because wikis are free to edit, it could be attributed to human error (on the harem side to be specific, since I just checked Sakura's page... because 6*s in general have around 15k-16k HP when evolved and maxed; 13k is like gold tier).

Is it a better idea to have an team with more 5* and 4* girls but that doesn't cover each attack type, or to include a couple 3* girls so that you have all four covered in each team?
