A much-used seafloor core compilation put the length of the ice age in this time period at , years, but this new record shortens that to about 92, 10 years. That shortened timing makes the end of both glacial periods (that is, the start of warming) line up with a peak in the tilt cycle, but only (one) of them lines up with a peak in the , year-long precession cycle. So this indicates that the tilt cycle was still the dominant factor, as it had been in the shorter ice ages previous.
But rather than look at two overlapping piles of spaghetti, they mixed the effects of tilt and precession into a single curve, laying that up against the full climate record. The result shows pretty obvious peaks that correspond to major warming events quite nicely. And that fits the varying length of recent glacial cycles, which were each between , and , years.

Red vertical lines highlight the timing of significant warming events (including some smaller ones that did not fully end the ice age). Age is shown along the bottom in thousands of years.
