But Grayson cautioned: "A seven-point advantage is a really good position to be in and we have given ourselves a platform, but we are there to be shot at.
"The only time I will be truly happy that we are seven points clear will be when there are two matches to go."
On the game itself, the Leeds manager admitted: "It was a boring first half - a bit dull and flat - so we had to raise the tempo. The second goal relaxed us and we produced a really good second-half performance.
"Yeovil did well in the first half, which could have gone either way. They are a good young team who can play with a lot of enthusiasm and quality."
