I rarely pass judgement on things of this nature prior to the report however ;
If the aircraft was 1000 ft low & there was no issues.
One has to wonder why the crew would climb back up the 1000 ft to 7300.
Wait for the report I suppose.
Corrective action? Can't imagine figuring out that they may have made an error and then saying " oh well we're here now so lets just continue.."
Ditto for the report.
ps - not having a crack at you.
