Coaster, it will clear with time, and I don't think letting it sit will cause any harm.
It is, however, really important to get the amount of lees into the secondary for clarification. Here is why.
Lees carry an electrical charge. I don't know if it is positive (+) or negative (-). For this example, let's assume the lees are +. As we all know, like charges repel each other, and this repulsion works against the settling of the lees. There are actually two mechanisms at work here. First is the charge repulsion. The second is particle size. Intuitively we know that a pebble falls faster through water than a grain of sand, which falls faster than a particle of clay.
[Apologies to Sir Isaac Newton, but he was wrong. Smaller (and less dense) objects fall more slowly through air as well. Think of a raindrop and a snowflake. It's just that what he was using in his experiments were not different enough to observe the differences. Thank goodness, or we may never have understood gravity.]
The smallness issue continues to smaller and smaller particles (some mining waste will take 50 years to settle) until Brownian motion takes over and stops settling all together. That's why pectic haze never clears.
Particles naturally want to get together and hold on to each other (like kids at a frat party). The purpose of a clarifying agent is to neutralize the charge so they can do just that (the purpose of wine at that frat party - ironic, huh?). What clarifiers like Insinglass and chitosan do is neutralize the charge on the particles.
The next thing that needs to happen is that the neutralized particles need to bump into each other so they can "hook up." That's how the particles get bigger. The more of them that there are, the higher the chance they will bump and attach. Any water treatment plant guy can tell you that almost clear water is the hardest to clarify.
Even the "some of the lees" that you racked over is enough for the bumping/attaching. However, the quantity of clarifier is geared toward the total quantity of charge that needs to be neutralized. The net result of reducing the quantity of lees prior to clarification is that the particles were overcharged, converting them, in our example, from + to -.
They will settle, but they will be very light and fluffy, Once they have settled, rack the wine and add a very small amount of bentonite. Bentonite acts differently from other clarifiers. It is actually a very porous mineral that sucks tiny particles in and creates those large particles needed for settling.
My brain hurts. I haven't thout about this stuff for years!
