Paul Cook was not getting carried away after seeing his Chestefield side move two points clear with a 4-1 drubbing of Cheltenham.
The Spireites rattled in four goals in seven and a half first-half minutes to seal all three points just as the game reached the half-hour mark.
Dan Gardner rifled in the opening goal with Eoin Doyle doubling the lead within a minute. Further goals followed from Ollie Banks and Liam Cooper as the visitors romped into an unassailable lead.
But it was a more determined Cheltenham side after the break, with Byron Harrison reducing the arrears early in the second half when he turned home a corner.
More could have followed for the home side had it not been for a string of good saves from Tommy Lee.
Despite the performance of his team, Cook did not get carried away.
He said: "It was an incredible spell for us because some of the goals were very, very good but we certainly won't get too excited.
"The first-half performance was probably as good from an attacking team away from home as you will see all season. We had constant threat, pace and movement and that's against a very good Cheltenham side.
"Mark Yates' teams never lie down for anyone and you could see that second half, they deserve a pat on the back because it would have been easy for them to cave in.
"I am lucky to be Chesterfield's manager and I have always been very proud to manage all the clubs I've managed. It is easy to say how good a manager I am when we have won but I will be keeping my feet on the ground."
