What is the drift expected if the 5.1ohm resistance is not soldered?

I'm very fearful of bricking my board by soldering the resistance to the board. The blog post mention the resistance is needed to prevent a clock drift.
I was thinking of just run it with the battery pcb and setup a NTP to clock syncing. My understanding would be that the drift would only happen during reboot.
Am i right?

The RTC will be constantly drifting, so if you restart the OS it'll get a wrong time from the RTC (even is the OS then counts the time at the right pace)
If you do not really want to solder this resistor in, there's another option also mentioned in the article - you can use the community version of the firmware that has NTP added
If you do not plan to solder this resistor in, you also won't need the battery kit, really - there's no point in counting the time when the board is not powered if this counting is off (the pace is wrong)
