Brett Taylor has warned his London Scottish side not to be complacent when they take on basement boys Havant on Saturday.
Scottish opened up a seven-point lead at the top of National Three (South) on Sunday with a 38-17 win at main title challengers Ealing.
They came from 10-9 down at half-time to win through tries from Rory Damant, Ledua Jope, Grant Livingston and Rory Greenslade-Jones, plus 18 points from the boot of James Brown.
But Taylor said: "The second-half was probably some of the best rugby I've seen our side play, but they key to any successful side is to be a chronic achiever week-in, week-out."
Scottish's victory allowed Rosslyn Park to close the gap on Ealing in third place with a low-scoring 6-3 win over Bridgwater & Albion.
In a game devoid of any tries, two Dylan Pugh penalties were enough to win it for Park.
But revenge will be in the air for Park when they take on Worthing on Saturday.
Last season, as a London One side, Worthing became the only side ever below national league level to knock Park out of the cup.
Now, with Worthing having been promoted, the two sides are National Three (South) rivals.
But Richmond softened Worthing up for Park with a 19-5 win last Saturday.
Gavin Hart, Andrew Wehbe and David West scored the tries, and Matt Hart converted twice for Richmond, who visit Barking on Saturday.
