Eight more goals at Leiston.
It took their total to an astonishing 24 in four games in their matches to date although, despite the scoreline, they were made to work hard by the Suffolk side to earn the right to victory.
Indeed, with two minutes of the first half remaining, the U's were only one goal to the good with the home side having had chances of their own.
But the U's fitness told in the second half with Freddie Sears continuing his outstanding pre-season form with four more goals taking his tally to nine so far.
The first goal came after just five minutes. A Gavin Massey cross saw Dan Holman leap the highest to add a header to his right footed finish against Brantham and his left footed goal against Sudbury.
The former Braintree man continued his assault on goal with three or four more chances in the first half, whilst Gareth Heath went close for Leiston.
The home side had a shout for a penalty as Walker rushed off his line and caught an opponent, but the referee waved strong appeals away.
With 34 minutes on the clock, Dominic Vose forced a fine full length save out of Danny Gay, before Sammie Szmodics sidefooted just wide of the post.
They did get their second on 42 minutes as Massey shifted the ball to the side with one touch and slammed home via the underside of the bar with his second as he kept his personal goal tally ticking over.
The winger missed a gilt-edged chance from close range shortly afterwards, but Holman then set up Szmodics, who lashed home from just inside the box.
There were eight changes at half time, but it was the hosts who scored next as Heath got the goal his efforts deserved after the U's let a ball get across the area for the midfielder to lift past Lewington.
However, as at Sudbury, the U's fought back immediately - and in some style.
Twice in two minutes, Sears bore down on keeper Gay and, on both occasions, he had the wherewithal to lift it over the shot stopper and into the net to make it 5-1.
Midway through the second half, the U's further extended their advantage as Drey Wright, introduced on the hour mark for George Moncur, held off his man from a Tom Eastman ball over the top to stab the ball home.
Sears was not to be outshone though and completed his hat-trick as he opted to round Gay on this occasion to slide home for his third.
David Wright fired over the bar, before Lewington reacted well to deny Leiston sub Leverett at his near post.
Alex Gilbey was felled late on to stop him converting a Wright cross, with Sears slamming home the set piece to complete another good day.
Tough tests await in the coming seven days, which will give boss Joe Dunne another viewpoint on his side who have shown no nervousness in front of goal so far.
