Just had a chance to see the spreadsheet and that's exactly my first thoughts. However, since Ty1on took the time to build this data, I'm sure it has value to him. I would really like to know the major goals of the project and who is the targeting audience?
On the three Timeshare Calendar tabs, you could easily build drop down boxes at the top of one worksheet to filter on the checkin day and the year. That would allow you to have just one sheet instead of three.
I'm sure I'd have other suggestions, once I knew the answer to the questions above.
Now those are questions an analyst would ask.
My purpose was to make a tool that saves myself from leafing through the member guide to find stuff. I have also input the other info about resorts into the database as I built the points data, but including that stuff would be my very last priority as I'm not sure it is that useful.
Also, I wanted to be able to look up maintenance fees, both weeks and UDI, without having to search for posts listing them. I found the tool you attached to be rather awkward for me personally.
The "Average of Avg Week Stay" is a tool that tries to put weeks and UDI on a basic apples to apples comparison, by taking a look at what it would cost you in MF, on average, to own a UDI sufficient to reserve the most basic 2BR unit. It takes the number of weeks in each season into account in the weighting. Of course the intangibles, like ability to reserve at other properties, can't be quantified.
I plan on making the TS Calendar a single sheet. This is something I made on the fly for someone, and I haven't built the algorithm to roll the Week 1 date up to the next when adding 364 to the previous year's Week 1. Week 53 will require an algorithm, too. If you notice, whenever the first day moves forward in day of month instead of back, I've hard written the date. This change is a low priority for me, as I really want to get the Weeks grouping on the points chart and try to make it as accurate a recreation of the MG points chart as possible.
There are also anomalies in the points charts I need to work out, like a couple resorts with multiple point spreads per season. For now, they are excluded.
So in short, my intention is to put decision support tools for the purchase and usage of Wyndham contracts in one place. There are some things that I will likely only do in Access, because they would require scripting to do in Excel, and I would not recommend that anyone enable macro execution for any file from a person they don't know.
