It seems that the most important sites were planned based on this scenario. Not all sites of course agree with this. Maybe the other ones were not ones planned by the civilizers, they were migrations. There are no written records about prehistoric sites so we can be sure that a great deal of them have not been unearthed. I think this rule is a good to tool to home in on the important ones.
I have updated the table to include more sites. Apart from this I'd like to refer to Egypt. The distance of Elephantine is 1500 km so maybe Neolithic origins should be investigated. This distance is more or less a decadic sub-multiple of the distance between the Earth and the Sun(147,090,000 to 152,100,000 km). This agrees with the el-Badari culture distance (1490 km). Also the Giza pyramid distances are a decadic sub-multiple of the distance between the Sun and Saturn.
Based on the table we would expect to find an important Neolithic site somewhere between Petnica – Obrez and Vinca – Strasevo in Serbia. Also a little to the east of Mehrgarh Pakistan. In India the area between Jhusi and Lahuradewa should be checked.
Research could also be extended to China where detailed site coordinates are hard to find. Peiligang culture near 6000 km, and Bashidang near 6200 km stand out.
When we move from Neolithic sites to early Bronze age sites we should be sure to change to point or reference. Thus if we move a little to the east from Tell al-Ubaid to Ur , we notice that the distance from Bronze age Dholavira(India) is closer to the 2500 km distance, also the distance to the Malta temples is close to the nominal 3000 km.
