The come-from-behind 36-22 victory over Sydney Roosters was the Eels' third win in four matches since Brad Arthur took the reins as caretaker coach.
And Hindmarsh, serving his final few games as Eels' skipper before he retires at season's end, says he has no idea what is behind their purple patch.
"It is good to win - pity it wasn't there at the start of the year. I don't know why, but we are winning games so it's a good feeling," Hindmarsh said.
"I don't know (what the difference is). We have been working on the same thing all year and I don't have an answer why it is but I will take it - we are winning games. That is enough for me."
The Eels followed impressive wins over top-eight aspirants Melbourne and Brisbane with a loss to Wests Tigers before bouncing back against the Roosters.
Parramatta led 18-10 at halftime on Saturday night before the Roosters grabbed the lead back with two tries in three minutes to hold the ascendancy with 30 minutes left to play.
Maligned halfback Chris Sandow then came to the fore for the Eels scoring two brilliant individual tries in the 57th and 65th minutes to give Parramatta just their sixth win of the season.
Hindmarsh said the fightback centred on the Eels attempting to enjoy their football again.
"I have made a conscious decision - win, lose or draw - to try and enjoy myself and try and soak up the last couple of weeks," he said.
"I think we are in a position where everyone can do that. The wooden spoon is still around but we are not pushing for finals so everything is just so much more relaxed."
Despite the win, Parramatta still sit in last place on the NRL ladder on 16 points, behind Penrith on for and against, who have a game in hand against Canberra on Sunday.
The Roosters sit one rung higher in 14th place with 19 points, and remain a wooden-spoon contender alongside the Eels and the Panthers.
Roosters' coach Brian Smith accused his team of not "playing hard enough".
"In the end, it was very disappointing," said Smith.
"There wasn't enough quality in our performance out there - not enough strength, not enough speed. You put in a performance like that when you don't play hard enough.
"We didn't work hard enough to get the points."
