 Excellent question. Let me dig into the hard architectural problems that make multi-client support for
  JDT-LS genuinely difficult:

  Searched for 10 patterns, read 2 files (ctrl+o to expand)     
                                                                                                              
● Based on my exploration of the JDT-LS codebase, here are the major architectural sticking points for
  multi-client support:

This will demonstrate that somehow, the off-by-half or 2x error is our fault, somewhere in our code. 
This simulates an actual run from the wbtc-ust pair.
When using 18, 8, or 6 as the decimals, there's a very interesting relationship in the output. 
I know this logic was copied from somewhere, and it's likely in use in several places.
