Quite pleased with this: Very small lambda errors in my latest map

[dnb]

Here's a set of histograms of lambda error for all the points in my VE table as extracted from a recent data log. 
(error is defined as actual lambda - target lambda)



Note the errors have zero mean, and a fairly small variance, so lambda correction works very well, and my VE table can't be that far out either...

Awesome
