my 2 cents:
40 years ago (or so), when you would crank your automobile on a cold morning, you would typically allow a few minutes for it to warm up and quit sputtering. More recent times, this is less noticeable.
The market for thinly trading options seems to exhibit a similar ("amateur? time", during the first few minutes of a days trading). Some people avoid the first few minutes of trading, others do not. It may also depend on what kind of trades you are placing. For example, if you are opening a new complex multi-leg option trade, waiting until pricing normalizes a bit may be preferred (since you are layering multiple pieces, and would prefer an atomic entry). If you are placing a limit order to get a "good" price entry (or exit), this could be an ideal time to try to get a fill.
"prices are not accurate" is probably not a reasonable description of what is happening, perhaps increased volatility would be more appropriate reference (IMHO)
PS: When placing an option order (buy or sell), it is preferable to never use a market order, but use a limit order if possible to restrict your fills to the outcome you deem acceptable.
