Of the 400 draft 11 calculations, 389 (97.25%) have been completed; only 11 (2.75%) remain:

1 d4 Nc6/Nf6/Nh6
1 e3 Na6/Nc6/Nf6/Nh6
1 e4 Na6/Nc6/Nf6/Nh6

To do the above draft 11 positions, about 76 draft 10 calculations and about 293 draft 9 calculations remain.

The parallel calculation of perft(11) for 1 e4 Nh6 is almost complete.

As a check on the main run, I had a separate machine calculate perft(11) for 1 e4 Nh6 using 120 bit hash codes. The count is: 8,439,066,785,081,361.

The corresponding result from the main run should be available in a few days. There are only 63 draft 10 and 215 draft 9 calculations remaining.

Of the 400 draft 11 calculations, 391 (97.75%) have been completed; only 9 (2.25%) remain:

1 d4 Nc6/Nf6/Nh6
1 e3 Nc6/Nf6/Nh6
1 e4 Nc6/Nf6/Nh6

To do the above draft 11 positions, about 50 draft 10 calculations and about 117 draft 9 calculations remain.

Of the 400 draft 11 calculations, 392 (98%) have been completed; only 8 (2%) remain:

1 d4 Nf6/Nh6
1 e3 Nc6/Nf6/Nh6
1 e4 Nc6/Nf6/Nh6

My guess is that if there hadn't been any power interruptions since the main run started, then it would have completed a couple of months ago.

I have modified my work estimation script to ignore records which are duplicates modulo the half move counter. The change in the numbers is small, but is significant when only a few percent or less of the total work remains.
