Evaluate the drafted changes
This is a difficult article to expand on without a deep geophysics and stratigraphy background. Nevertheless, many topics were successfully introduced.

I noted the following limitations.


 * 1) Punctuation errors and typos are abundant. Please review. In any case, wording can be simplified to help with that.
 * 2) The structure of the article can be adjusted to serve the reader that may need an explanation of several concepts before being able to understand orbital tuning. i.e., Lead; orbital cycles; geochronology; uses; criticism. I think that briefly explaining orbital cycles and geochronology will help the reader greatly. Emphasis should be placed on the relevant orbital cycles and the limitations of geocronological techniques that make orbital tuning a requirement.
 * 3) I think you have the concept upside down, as I read the paragraph in Description. Right off the bat, the second paragraph has no relevance and seems copied. Second, orbital tuning has to do with physically calculated cycles that the earth goes through and is used as the basis for adjusting the age model of paleo records with poor dating. These paleorecords and their dating techniques are prone to errors and uncertainties and for this reason, they are sometimes adjusted to fit on known astronomical cycles when and where they have salient features in common. In other words, proxy records may feature ups and downs that may be slightly shifted with regards to the ups and downs expected from changes in solar irradiance changes, for example, so orbital tuning slightly shifts those ups and downs in the proxy record to line up with those of the solar irradiance changes.
 * 4) The last section does a good job of explaining why proxy records have their pitfalls and require orbital tuning. However, wording gets messy and the flow of these paragraphs is hard to follow. It should also mention that it could be tautological to make any inferences about synchronous changes, when a record has been orbitally tuned to appear that way.

Good work and the article is on a good path forward.
