The results are not skewed by letting the AI continue to produce more after an initial decision of what to generate. The AI cannot look back and modify previous output generated. The only “skewing” would be from the lengthier prompt itself.
It is not in doubt that you can send the input and get the output. It seems that ChatGPT just “loves”, or doesn’t have any refusals on tap. Maybe that sycophant attitude helps lmsys
user satisfaction benchmarks.
We can get more information from examining logit probabilities when using the API, and the model “chatgpt-4o-latest” which is supposed to be what ChatGPT uses. Controlled input and conditions, and a wider swath of the underlying generation is a better experiment.

0.999… means it is is going to produce that with exceptional regularity over 99% of the time.
Cut from the same cloth as the newest API model:
“gpt-4o-2024-11-20”
‘Yes’, bytes:[89, 101, 115], prob: 0.977845
‘As’, bytes:[65, 115], prob: 0.015805
‘Sure’, bytes:[83, 117, 114, 101], prob: 0.005131
‘No’, bytes:[78, 111], prob: 0.000421
“I’m”, bytes:[73, 39, 109], prob: 0.000328
‘AI’, bytes:[65, 73], prob: 0.000094
‘I’, bytes:[73], prob: 0.000083
…
A massive shift from a similar API model of higher cost, where the ranking “Yes” is under 4%:
“gpt-4o-2024-05-13”

You can imagine how the response would be completed on each of those possibilities. “As” is completed “As an AI, I don’t have feelings, so I can’t love.”
