I have some insecurities on the subject too. So for example, if I want to start a meditation program on a specific date:
1. Does *starting the program* during the VoC affects the outcome?
2. Does *planning a meditation program* during the VoC affects the outcome?
3. Taking a decision about *when to start* during the VoC affects the outcome?
4. Does any kind of thoughts about the meditation program during the VoC affects the outcome?
Also, on the website says that plans made during the VoC are affected, so is there a difference between taking a decision and making a plan?
Finally, which meditations can be done during the VoC and which not?
Generally, you should not worry so much about this. It is impossible to get around the VoC sometimes. As long as you don't start something large or spiritual in nature during the VoC, then you are fine.
For your questions, focus on what has been started during the VoC. If you started the plan of something, then only the plan would get influenced. For example, maybe you will rethink it later. It does not mean that your plans will be totally destroyed or worthless. Or, there might not even be a perceivable difference, especially with something minor.
The VoC is not going to totally warp reality in the sense that any thoughts you have are equivalent to delusions or something useless. Nor does it inflict any permanent damage just because you thought of something without meaning to.
If you accidentally drafted important plans during the VoC, whether on paper or in your head, then simply remind yourself to take a second look at them afterward. More importantly, do not actually start anything important during the VoC.
-------------------------
Anything can be continued during the VoC, just not started. For example, continue your aura cleaning, yoga, any workings, and so on just as normal. Perhaps if you wait too long, like a few days between an exercise, it is best to wait until after the VoC, however.
It is not totally clear how to restart something if it was accidentally started during the VoC. Maybe, this is not even an issue. But, if it is an issue, you can tweak the activity to be something slightly different. For example, change the affirmation a bit, alter the energy used, or something.
