Yes i would agree, card 6 has an effect on the outcome of the situation, but as the reader, even with the CC, if the wheel sits in the outcome and the 6 th card is a minor, you would have to point out quite strongly that the positive outcome would depend on the querent making full use of any opportunities that might open up for them.
Also there could be a considerable amount of time for the querent between the recent future card 6 and the possible outcome card 10, giving this situation time to change in any direction if the advice of the cards are not carried through.
This major would then carry the most weight and the current situation could continue to be changeable.
If the wheel comes up as an outcome in any other spread where it does not have the benefit of card 6, then this card would have to be read very carefully, for example if things have not being going well then this card could provide a welcome change, if the opposite applies then there could be a possibility that things might well change and you could experience a period of bad luck.
I had some experience of this a few years ago. I did a reading for someone who had been experiencing a few problems within her relationship. The wheel sat firmly in her outcome slot.
Her relationship had been very up and down, at the time of her reading they had just got back together, I did a 5 card spread. The spread reflected the changeable circumstances of this relationship.
The undertones of this because of the wheel, I felt, where all about destiny, they came together by chance, there was a chance it could work but then every chance it wouldn't, it was the only major in the spread.
I felt that as they where together at the time of the reading, chances where that they might not stand the test of time. So I said that it could go either way, if she wanted it to work she would have to make sure she made the most of all the possibilities that might come her way.
A few weeks after, they went their separate ways. It turns out that he was offered a short term job abroad and despite her going out to spend time with him, it became clear that it just was not meant to be. Incidental the hidden influence card was the knight wands. Generally a positive card, no reason to expect anything negative as such.
I suppose we all have to go with our original feeling of the card at the time of the reading and chances are it could be slightly different for most of us. So whatever we read or are told by others we then have to slot it in and blend it with our own feelings and experiences with our cards. Otherwise we end up confusing our cards and how they work with us.
Sorry this is so long winded thought you might find this experience I had with this card useful.
