I am noticing an interesting inconsistency between the counts found in the Concordance Tool and the Root Guide found in the Bible Word Guide (and now as a separate guide on its own). For example, if you run a Concordance Tool report for ROOT in the New Testament (with results grouped by lemma) it shows the root λέγω occurs 3044 times, and the lemma λέγω 1328 times. When looking at the root λέγω in the ROOT GUIDE, the spark graph shows the root λέγω occurs 2984 times, and the lemma λέγω 1292 times.
The word ἔρχομαι has the opposite problem. The ROOT GUIDE shows a higher count than the Concordance Tool. The ROOT GUIDE shows 1398 occurrences of the root while the Concordance Tool shows 1396.
I am finding this is the case with most roots.
Can someone help me understand the differences between these two tools results?
P.S. - my computer in not indexing
