The Hammers have undergone a revival in recent weeks.
Jarvis told West Ham TV: "I think we're on almost the same points as we were at this stage last season so it's a turnaround.
"We had such a good start last season that it really helped keep us up in the top half and when we had a little dip it didn't matter as much because we were still high up in the table.
"This season we've been a little up and down in the table but it's nice that we're on a high at the moment and hopefully we can continue that."
