Are OPK wands more reliable than the CB OPK Digitals?

Sorry ya'll...one more opk question!! Haha I just started testing with the wands and CB advanced digital this weekend. Up until Friday night I was only using the regular CB digital. I first used CB advanced Saturday morning and got "low fertility" but I was super confused because the wand was SUPER positive (yes, I've been using both lol). So I posted and someone said that first use can say low fertility because of a memory bank thing and it needs to create a baseline. So I tested again later that day and got "high fertility". So now the wands have returned to being negative but I'm still getting "high fertility" on the CB advanced. Could this be because I didn't start them until I was already high fertility so it's throwing off my baseline somehow? I do also notice that there is always a run in the dye when I eject it...possible false "high fertility"? Anywho, I guess my question comes down to: are the wands more reliable than the digi tests? If so I'm pretty sure I ovulated on CD22, right?
