Turntable leveling


Pardon the possible obtuseness of the question, but - in the opinion of forum readers - how important to sound quality, LP and stylus wear is having my turntable precisely level? Try as I might, I can't get it <2 degrees from absolutely horizontal measuring with the Levlx iOS app though it looks good with a bubble gauge. I've looked online and I can't find a consensus opinion on this matter though I know the more level the better.
Thanks in advance,Keith

You can by a record clamp with a bubble square over the thing that you put the record on . Easy to make it perfect, had  one for at least a decade .
Starrett 98-12 precision bubble level, Amazon $219. Tell ‘em Willie Boy sent ya! 
$219 for a bubble level seems a bit pricey for a non-pro but I suppose I'd want a builder to be using the best possible for the job.
This particular weight isn’t very heavy, but the bubble level is pretty handy and it's very affordable as far as weights, clamps, etc. go - https://echohifi.com/details/12083/Echo-Audio_Record-Stabilizer
