Thx. You can write review here https://mining-bios.eu/product/polaris-bios-editor-3-pro-pbe-3-pro-performance-timings/#tab-reviews 
I don't have any Vega, my friend is developing Vega bios editor, but he is stuck and probably won't be able to decode the timings. From what I know even Wolf0 and Eliovp weren't able to do it.
There might be support for RX500x series if it ever will come out not just OEM and we will see what RX600 series will be. RX650/660 or so might still be Polaris but high ends will probably use GDDR6 instead of GDDR5.
