Yes indeed! The TLE issue number can be seen at the end of the first line, now you can see 437, ignore the 7 ( it's a checksum) so it's number 43.
Yesterday I received an interesting email from someone who deals with TLE's professionally. After a satellite manouvre, the first TLE issued after that may be a bit inaccurate. So if the satellite operator after that leaves the thrusters alone, the later TLE's should become more accurate.
Geo TLE's are only based on optical tracking, that explains there will normally be no more than one update per day.
