Anyone worked out the Clearance in/out formula?
Original post by GeorgeB16
I've just had a look at that and on the "selection" sheet, it gives the sights and a variety of times. Are these supposed to be clues or what? If I'm being honest, I don't even know what the **** I need to do


I assume they are supposed to be clues, I haven't quite worked it out fully yet however, if I was to give a tip, I would say annotate the spreadsheet, it really helps and add the map to it and link it to the spreadsheet. Remember that the pre release is the biggest clue, add bits and bobs from the pre release on to your spreadsheet

what does clearance mean??


Clearance in and out are the columns on the selection sheet which go red and have an N for no and Y for yes.

thanks, but what does clearance mean? like the depth in and out refers to the height of the water...

As far as I believe clearance is the space above the boat ( e.g if they go inside fingals cave then they need enough headspace to move about )

Anyone find flaws in the models?
For activity 4 to evaluate the model we are often asked to suggest improvements for the model in the report..
Also for Tide in and tide out, why cant we just use a vlook up instead of an INDEX MATCH


If you mean tide start and tide end I've been practising and using a vlookup?

I think the formula will be along the lines of:
Depth In - '=IF(J14<Sights!D12,"N","Y")'
Depth Out - '=IF(K14<Sights!D12,"N","Y")'
Clearance In - '=IF(J14>Sights!E12,"N","Y")'
Clearance Out - '=IF(K14>Sights!E12,"N","Y")'

Has anyone got any clues about the 2 hidden sheets????

Personally I think they are there to show how the model was evolved.

I tried to add the October tides to the model but their is data missing or the data is in the wrong place.

What i have been thinking is that for tide start and end, all you have to do is vlookup the table to the left to find the name of the place and then display what it says. For depth in (dont know if it is right so dont believe me!)you use an if statement to look up whether tide start is bigger than (in sights worksheet) the "lowest" value of the corresponding location -if it does then y will be displayed- for depth out its the same except switch tide in to tide out. Clearance is the same, except see whether the tide start/end is smaller than the "highest" values. any critique would be appreciated!

Hi

I think thats correct as that is what I done as well

Any ideas about the two hidden sheets ???

From what I can tell it uses sin and cosine, and could be part of the october tides. We could get given october tides as something to add to the database later-but who knows tbh, just keep going through the spreadsheet I guess and practise importing data and using the formulas.

why are you repeating the condition in clearance; you are checking for the tide to be lower than the highest value in sights worksheet, but that is already tested for depth in/out in your IF(and( formula.

So dont you think it is better to use the fromula:
Depth In - '=IF(J14<Sights!D12,"N","Y")'
Clearance In - '=IF(J14>Sights!E12,"N","Y")'

that's exactly what I am thinking about, but dont you think there needs to be a nested if there somewhere in either depth in or clearance in checking for it to be higher than the lowest as well as lower than the highest.

I was looking at this the other day, I would say maybe to add a reset button on the selection sheet to remove the routes in one click so the next month can be inputted faster. Also maybe to hide any sheets which don't need to be changes frequently as there are a lot of them.

Does it need to be as complicated as that though? This is what i did for depth in:
=IF(J14<Sights!D12,"N","Y")

The clearance could be very similar or if we are given a min clearance then you could do something like:
=IF(J14>=$Q$14,"Y","N") The Q14 is just a cell where i've added a min clearance.


Any thoughts?

Why have you used IF AND? Is it needed? I've attached my opinions if you'd like to compare?
What day is everyone doing their exam?

Does anyone have any ideas about what to put in the report?
Are we not going to have to use the October Tides in the exam? I heard people saying how instead of the data we have, we'll have to use october's. Im so confused

Anyone had any luck with working out tide heights using sin and cos?
