There is a new "non-partisan" analysis of Michigan voting data conducted by multiple unpaid citizens and volunteer experts.

First they looked at the shift in voting patterns that occurred between the 2016 and 2020 elections to identify suspicious counties. The two with the largest shifts were Oakland and Wayne.
After plotting each county they examined the correlations between Election Day votes and absentee votes. Trump's results correlate while Biden's votes skew overwhelmingly for absentee ballots. They call this a "serious statistical aberration."
Looking at Wayne county again they find that since the 2016 election the county has allegedly shifted 15 points in favor of the democrats.
They identified several townships in Wayne county that are anomalous. In one township, Biden gained "151% of the new registered voters and 97% of the new votes above 2016."
