After putting ad limit on my website, I watched a video tutorial of yours on YouTube, where you said that if you start the experiment of turning off auto ads, the ad limit will be gone in 15 to 20 days. I have done this as you said. Now after 24 days my ad limit issue is resolved. But Google kept the original or what does it mean by this text, please tell me a little. Is this a problem or is it already coming? Will it have any impact on earnings?

I’ve given you two screenshots to illustrate the point, the first of which is towards the end of your YouTube video, where you re-turn off the auto-ads turning off experiment. Where it is written, you have kept the original.

And the 2nd screenshot is of my AdSense experiment page where it says that Google has kept the original.
Please explain what it means.
