Yes, the bandwidth authorities measure the bandwidth, then calculate the ratio between the advertised and measured bandwidths. This becomes the consensus weight (after averaging, and then taking the low-median of votes). Clients choose relays based on consensus weight, which then affects the bandwidth they carry, which affects the observed bandwidth, which is one of the factors that feeds into the measured bandwidth. Part of the calculation process for the consensus weight makes sure that this feedback converges, rather than diverging.

smells like a feedback formula + weighting to ramp on new relays. - -- Toralf PGP: C4EACDDE 0076E94E -----BEGIN PGP SIGNATURE----- iHYEAREIAB4FAlhP7sMXHHRvcmFsZi5mb2Vyc3RlckBnbXguZGUACgkQxOrN3gB2 6U4TSgD/Tw7TcOZDVbBKfMGjcf/51z2wm6fXO9XsNvBtgB9vlgEA+QFD0ExdfW6L xQQsA6+WBFqTBhZXpbrUBh9WS3FM8MR9 =MDeJ -----END PGP SIGNATURE-----
