+### Names TTL extension is relative (issue #228)
+
+`wraith-names::extend_name_ttl` and `bulk_renew` take `extend_to` as a TTL in
+ledgers from now. Before, the contract passed the current ledger as the
+`extend_ttl` threshold, so in the bench the contract instance top-up was skipped.
+It is now performed, because the threshold is `extend_to`. `extend_name_ttl::existing` goes from 61,349 to
+63,741 instructions (+3.9%) and from 5,506 to 6,354 memory bytes (+15.4%, about
+850 bytes). Ledger entries, read/write bytes and event bytes are unchanged, and
+no other benched op moves, including `bulk_renew` (which does not extend the
+instance). Dropping the instance top-up brings the op down to 57,407
+instructions and 5,118 bytes, but then the keeper would extend names while the
+contract itself could expire, so the cost is the extension doing the work it
+was meant to do.
