Mean time-to-target for S8 4D RU controllers per test batch

Time-to-Target Average (s)
Months Post-training	Batch number					Std. Dev.
	1	2	3	4	5
1 Month*	6.6	11.6	8.4	9.5	12.5	2.4
1 Month	8.2	10.5	15.1	13.1	13.8	2.8
4 Months	7.0	7.7	8.0	9.6	10.3	1.4
6 Months	7.0	8.4	6.6	8.2	6.6	0.9
9 Months	7.9	6.8	10.1	8.5	8.7	1.2
Kinematic	7.3	6.5	5.7	5.7	6.1	0.6

Values in the central 6 × 5 grid are mean Time-To-Target, with missed targets excluded. The rightmost column shows the standard deviation across batches. Evaluations 4/6/9 months post-training appear to have more consistent rates between batches than both 1-month post-training evaluations
