Every site should Chrono, no if or buts its an absolute MUST!
What i would propose is that each site Chrono at the start of the day every players gun (1)
By every gun i mean AEGs, DMRs, Bolt action Rifles and PISTOLs (2)
Use a sites magazine preloaded with a known weight, either 0.20g or 0.25g and the Chrono matched to those weights (3)
Use the players preloaded magazine with their weight which they must declare, it should fall within a certain speed on the chrono (4)
Use Joules NOT FPS or MPS (5)
1: Every player needs to have their gun chrono'd, regardless of whether they are a regular or newbie, using their own gun or a rental, this includes marshals or staff who want to play the occasional game.
2: I mean every gun to be used that day or potentially used, i included Pistols as some people field CO2 Pistols which can occasionally be way too hot for Airsoft play.
3: If a site uses its own preloaded mags in popular mags such as STANAGs, AKs, G36 etc with the sites known weight then this reduces the chance of people going up to the Marshals and saying "yeah i got 0.20g BBs loaded" when in actual fact they have 0.30g BBs and hitting an FPS of 345 which would put them shooting at 1.6joules (around most sites DMR limits)
4: Chrono the gun again using the players declared weight, if the player says he or she is going to be using 0.25g BBs and if their gun clocked in at 345FPS on .20g BBs then it should clock in at around 310FPS on 0.25g BBs, this is to prevent Joule creep as you go up the BB weights.
5: Use Joule and NOT FPS or MPS as in reality what the UK legislation regarding Airsoft guns speaks in Joules not FPS.
6: Each gun to be chrono'd must have its Hop Up set to the lowest setting.
I'll admit on points 3 and 4 you may have a problem with having a variety of too many magazines or some players turning up with weird or hard to find mags such as a Kriss Vector Mag, if thats the case the site should have a speed loader with a known weight of BB ready, the player should provide an empty mag of theirs, which should be loaded up with that BB weigh and tested.
Furthermore, to prevent any discrepancy all sites should use the same Chrono brand and make, most of the sites i have visited use the Xcoretech X3200 and whilst i perfectly understand that not all chronos are made equal even among the same make it helps to reduce discrepancy. Some of my guns are shown just below the 350FPS limit on Xcoretech but on others such as Madbulls is shown around 325FPS (what gives).
All my above points is to try and prevent players from cheating the Chrono.
As for HPA setups, definitely use tournament locks with serial number zip ties, what prevents a HPA user from arriving to the site with a handful of coloured zip ties, get chrono'd with a legit FPS, get tied by staff, goes to the safe zone, removes the staffs tie, turns up the regulator and puts his own tie of similar colour through the regulator as if to say that it was chrono'd ok.

I agree in principle, but it's never going to happen. Plus it's impractical, re-setting the hop takes ages with some guns.
Hop, takes at most 10% off before reducing an AEG to less range than a gas pistol, due to overhop.
Now if the hop was re-designed to 'click' like the one in the ASG scorpion, that'd be different.
That being said, the mall for example has a hard limit of 340, if it was hop off, most guns would fail. My MP5 is 'hot' with zero hop, but the range sucks.
Lowering the accepted max is better than wasting time and pissing people off with hop related issues.
I'm sure in some cases, such as M4, players would rather remove the upper and the inner.

Nope.
I spend a lot of time tuning the hopup even on my AEG. Not to mention that the bolties with VSR rubber don't even work with the hopup all the way down. The BB just rolls out. And as said, you will have way different output energy on different hopup settings. We should chrono with the gun set up as we are going to use it.
But.
There will never be capacity to do the perfect chronoing on a field (and have time to play too) so there will always be some trust needed. How much, depends on the site owners. If there has never been a problem and the players are not moaning, then most likely there are no fps cheaters. And players will start moaning as soon as there is something off.
I have been to sites where no chronoing was mandatory and there were zero problems and sites where every gun was chronoed and marked, but there were cheaters.

One of the reasons we shifted to using customer's ammo weights. Can you really expect someone to dial a PDI hop off for chrono and have it reset in time for the game?
Add joule creep to the mix and it makes so much more sense not to doggedly use a 0.2 for everything.
We made a chart up which gives the max fps for each BB weight at each of the three limits we use which stays with the chrono.
Check weight, check hop is set correctly with a couple of test shots down range, check fps, check it's within the limit on the chart. Simple.
Quite possibly the most painful hit I've ever taken was from a gun I know was running under 1 joule at about 20 metres away. The guy wasn't using anything heavier than a 0.25g but it hit me square on my skull and made an amazing crack sound. Luckily I have a very thick skull...
