The complex process of verifying and tallying votes is now in its fourth day, with Independent Electoral and Boundaries Commission [IEBC] chairman Wafula Chebukati accusing political party agents of delaying the exercise by haranguing election workers with unnecessary questions.
"We have observed that we are not moving as fast as we should. This exercise needs to be concluded as soon as possible," Chebukati said.
"The agents in this exercise cannot proceed in the manner in which we are proceeding as if we are doing a forensic audit.
"Please don't interrogate the... officers and slow down the process. If we do that, we will not be able to finish this exercise," he warned.
Chebukati has urged Kenyans not to worry about the different outcomes projected by various TV channels, saying the IEBC would release the results as soon as possible.
The IEBC, in a bid to be transparent, has uploaded forms to its website showing the results from each polling station, enabling Kenyan TV channels to work out their tallies.
But the broadcasters suddenly stopped their tallies on Thursday, with around a million votes left to go.
But with the wait likely stretching into the weekend, some Kenyans said they were increasingly anxious to know who the country's next leader would be.
Social media is already swamped with disinformation about the results, with rights campaigners and civil society groups accusing both candidates' camps of sharing misleading posts.
"We pray they announce, the earlier the better," Jael Akinyi, a retired librarian, told AFP on a busy street corner in Odinga's bastion of Kisumu.
Christopher Mesa, a pastor at the Africa Gospel Church in the lakeside city, said there was "a lot of anxiety about the results" among his congregation, and the conflicting results on television only served to confuse people.
"By not showing the results, it calms the people. That was bringing emotions up and down," he said.
"We would rather it takes time but it is clear. The delay is not a problem," he told AFP.
International observers, including from the United States, the European Union and the African Union, have hailed the IEBC for improving its procedures compared to earlier polls.
But turnout was lower than that seen in previous elections and some Kenyans said they were keen to move on from the vote and resume normal life.
No presidential poll outcome has gone uncontested in Kenya since 2002, and the disputes have led to bloodshed in the past, either involving ethnic clashes or police violence.
So far in the 2022 count, people have restrained from violence.
