Wednesday started their home game against Middlesbrough just one point and two places above the relegation zone and with the pessimists expecting the worst. However, goals from Steve Howard and Leroy Lita banished the spectre of relegation inside the first half-hour as the Owls ran out comfortable 2-0 winners.
Jones said: "This is a far bigger achievement than last year. Nobody will ever sway me on that because this has been a tough year for this football club."
"I think we've moved up about four places so when you look at the table it looks like an easy one.
"But it's been a tough one and I am delighted with everybody associated with the club. And that includes the supporters as well because that has been absolutely next to none."
Boro finished the campaign with just three wins in 2013. Of the season, while bemoaning an extensive injury list, boss Tony Mowbray said: "Disappointing for us: we could have gone top New Year's Day if we'd beaten Derby.
"So for 27 games we were as good as anybody in this league, for the rest we have struggled, we've won three of them so it should be no surprise to us we didn't get a victory here, we have to get stronger I think.
"Ultimately the squad has to be stronger and deeper and try and sustain it."
