Relativity Assisted Review Parameters

kCura recommends not using Assisted Review, or TAR, for data sets less than 50,000 documents. See page 10 of the Assisted Review Guide for version 9.5 of Relativity here. Compare this the Catalyst Predict system which can apparently employ TAR on sets as small as 8,000 documents. See here. Also note the kCura does not recommend using Assisted Review on document populations that consist largely of numbers - presumably those with a high percentage of spreadsheets.
