Not planning on installing without the tether, but wanting to understand all the ins and outs of the issue.
The Regent is the only one that requires tethering (unless you're installing your seats w/ LATCH and then you need to use the tether) at a certain weight. It is NOT covered under the same rules as seats that go to 65# so it doesn't have the same rules as far as head excursion etc. 65# and under seats must be tested w/ and w/out the tether and must pass both parts to be able to be sold. Does that help? I'm assuming they require tethering after 50# b/c of excessive head excursion, but couldn't tell you.
