A young-Earther would object to all of the "assumptions" listed above.
However, the test for these assumptions is the plot of the data itself.
Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.
Further, the oldest age determinations of individual meteorites generally give concordant ages by multiple radiometric means, or multiple tests across different samples.
For example, Henry Morris says: He lead to similar results, i.e., a rate virtually identical to the estimated production flux.
Another possible escape mechanism is direct interaction of the solar wind with the upper atmosphere during the short periods of lower magnetic-field intensity while the field is reversing.
Unfortunately, the age cannot be computed directly from material that is solely from the Earth.
There is evidence that energy from the Earth's accumulation caused the surface to be molten.
