The Ibrox side started 2020 believing they were set to end Celtic's reign of dominance after claiming victory at Parkhead.
Rangers' display at Kilmarnock had echoes of their 2-2 draw against Aberdeen at Pittodrie earlier in the season when they also failed to capitalise on getting into a winning position at half-time.
It is a similar story to last year's campaign when Gers entered the winter break on the high of derby triumph only to be brought crashing down at Rugby Park, allowing the Hoops to romp away to the crown.
Before they can do that, though, Gerrard's men will have to get to the bottom of what's causing their slump - but Tavernier confessed he is clueless.
Right-back Tavernier, speaking to the BBC, said: "I honestly can't answer for the last two Januarys".
"We've made it harder for ourselves, definitely". It was as clear as day.
"We're not getting out of the blocks at the start of the year and it's costing us". "To beat a team as good as Hearts with an emphatic scoreline like that was very pleasing".
Gers were sitting pretty at the break in Ayrshire after taking the lead with a Scott Arfield rocket. Celtic have a significant lead at the top and they are in sensational form as well. It's a long way to go and it could flip at any time.
Ntcham opened the scoring in the first-half for the Bhoys, as he reacted quickest to a goalkeeper save to tap in a rebound.
The Ibrox outfit fell further behind Celtic in the title race after a poor second-half showing and it will be interesting to see if they can make amends in the coming weeks. We've been conceding bad goals, it's as simple as that.
"We came here tonight and it was a pressure game in a stadium where you know you are going to be under the cosh or under the heat".
"We never get opportunities to score goals like that ever in a season and it's criminal we are conceding them as a team".
