I asked a friend and he gave me a good explanation, so I'm just gonna paste it here for others:
There is a simple and a complex answer depending on how much you want to understand the pricing dynamic of options. LEAPs don't react 1:1 with a stock move because the probability of your option being in the money at expiry is still very much up in the air so you basically don't get full credit for a move in the stock this far out from expiry.
The more complex answer involves a discussion of option 'greeks'. Delta, Gamma, Theta, Vega, and Rho are variables that affect the pricing of all options. The key greek in this case is Delta because it describes mathematically the expected move of an option as a ratio vs changes in stock price. For put options the ratio is -1 to 0 where -1 is direct correlation between stock price and option price and 0 is no correlation. The Delta increases as an option gets deeper in the money and also as it gets closer to expiry and reflects the probability of the option expiring in the money. For your option contract the current Delta is -0.5673 so -3.38 * -0.5673 = 1.9 which is close. Also keep in mind that that strike price had a last trade at 12:03 when the stock was at 13.3 and the current ask price is 22.30 so the last price isn't a true reflection of the market value.
As for the other greeks, Gamma is a reflection of volatility in the sense that it affects the rate of change of Delta as price and time changes. Theta is the value of the time component of the option and is expressed as the expected time decay per day. The problem is that the time premium is really some arbitrary number that the market maker seems to be able to change at will without justification and it can fluctuate wildly over short periods of time and I think this may explain some of the discrepancy.
If you bought the options when AAPL was $118.68 a couple weeks ago (option price of $18.85) and now AAPL is at $112.34 and the Delta over that time averaged at -0.55 then your expected option price would be $22.34 (($118.68 - $112.34) * 0.55 + 18.85 = $22.34) so you lost around $0.24 in time premium or 'Theta burn' over the last 2 weeks assuming it opens trading around 22.1 on Monday.
Your broker should have information about the option contract greeks somewhere. For my platform I have to put the cursor over top of the option contract for it to show me the greeks. If your broker doesn't have this then you can get it from nasdaq.com.
This is another reason that I only invest in deep in the money LEAPs because the time premium is much much lower than near the money and also because delta is much higher so if I want to trade out of it early I don't feel like I'm getting ripped off not getting paid for a stock price move. For example look at the Jan 17 175 put. The Delta is -0.9 and the time premium is only $0-1 depending if you are looking at the bid or ask. The only downside is expected returns are lower for deep in the money contracts and they are expensive to buy.
