409.01 dev work on error correction - 10x residual error strategy
409.02 error correction - 'nudge' correction strategy
409.03 candidate that might actually work
409.04 error correction working in test - needs more testing
409.05 testing error correction on OMC
409.06 fixed bug in multi-value set using strict JSON
409.07 corrected text mode work offset display
interim checkpoint
409.08 testing correction with less aggressive correction
409.10 tests various conditions
409.11 testing various conditions - initial direction = true
409.12 testing various conditions - initial direction = false, do not adjust accumulator for direction reversals
409.13 testing various conditions - changes segment length computation
409.14 testing various conditions - hard-wire segment time to nominal segment time value
409.15 testing various conditions - 409.14 plus no step correction
409.16	// testing various conditions - 409.14 plus threshold = 4
409.18 testing various conditions - some refactoring on 409.16 - no functional changes - threshold set back to 1
409.19 testing various conditions - some cleanup
409.20 testing various conditions - removed section target corrections in _exec_aline_segment() (plan_exec) for testing error contribution. Also code rearrangement to take advantage of fixed-time segments.
409.21 testing various conditions - re-applied section correction
