Frank Lampard celebrated a year in charge of Coventry on Friday and his side are dominating the second tier like few have done before them.
The Sky Blues have now won all five of their matches in November following their only league loss of the season at Wrexham on 31 October.
Their goalscoring is also unrivalled in the top four divisions of English football.
In 10 of their 18 league matches they have scored three or more times.
They have 15 more goals than the second-highest scorers in the Premier League or EFL – League Two MK Dons.
No side at this stage of the campaign has scored 50 goals since Sheffield Wednesday in 1958-59 and Middlesbrough’s second-tier record of 122 goals almost a century ago could also be under threat.
Coventry face tough away tests in their next two fixtures at Ipswich and Preston but on this form no one would bet against them taking six more points.
Despite the blow of conceding two quick goals just before the break, Charlton showed plenty of heart in the second half and Sonny Carey should have scored to make it 2-2, instead blasting over.
Once Simms had scored his second of the game and seventh of the season, Bobby Thomas almost made it 4-1 but his effort from distance struck the post.
A five-game unbeaten run before this losing streak means Charlton still have a six-point buffer to the drop zone.
However, Addicks fans will be expecting victory against freefalling Portsmouth next weekend to rebuild some momentum.
